A transfer-printing technique to integrate metal electrodes and 2D materials on a wafer-scale
https://techxplore.com/news/2022-06-tra ... es-2d.html
by Ingrid Fadelli , Tech Xplore
Metal-semiconductor junctions, electrical junctions in which a metal is linked to a semiconducting material, are crucial components for numerous electronic and optoelectronic devices. While they are now widely produced and used worldwide, creating good quality junctions that integrate conventional metals and 2D semiconductors can be difficult.

In fact, when applied to 2D materials, conventional metal deposition techniques, which entail a process known as ion bombardment, can cause a chemical disorder. In addition, existing transfer printing techniques, which involve the pre-deposition and transfer of metal electrodes on the surface of 2D materials, have been found to perform poorly due to the creation of chemical bonds on the substrate for the pre-deposition that hinder the electrodes' transfer.

Researchers at the Chinese Academy of Sciences, Hunan University, City University of Hong Kong and Fudan University have recently developed a new technique that could be used to transfer metal electrodes on 2D materials more effectively, enabling the development of more reliable metal-semiconductor junctions. This technique, introduced in a paper published in Nature Electronics, entails the delamination of metal electrode arrays from a graphene wafer, and their subsequent transfer printing onto different 2D materials.

Samsung Rumored to Begin 3nm Mass Production Next Week
https://www.extremetech.com/computing/3 ... -next-week
By Josh Norem on June 24, 2022 at 9:29 am

A news agency in Korea is reporting Samsung is about to make a major announcement. The world’s second-largest silicon foundry will reportedly enter mass production of its 3nm process next week. In doing so, Samsung becomes the first global foundry to reach this milestone in advanced node production. It notably beats its main rival TSMC to the punch, as the Taiwanese powerhouse isn’t expected to ramp 3nm until later this year. Intel will reach 3nm sometime in 2023 with its Intel 3 process.

The move by Samsung marks its transition from FinFet to Gate-All-Around (GAA) transistors. It’s the first major foundry to make the switch. The company says it will allow for a 45 percent reduction in chip area compared with FinFet. It will also allow for 30 percent more performance and will require 50 percent less power. Samsung has been developing its 3nm process for some time now and even showed it to President Biden recently. However, reports indicated it was suffering from poor yields. This is expected when developing a new process node. Still, it was reported it was only getting between 10 and 20 percent yields at 3nm previously. If it’s moving into mass production, also called high volume manufacturing (HVM), it has probably made strides on this front.

A fast and energy-efficient sparse Ising machine to solve computationally hard problems
https://techxplore.com/news/2022-06-fas ... chine.html
by Ingrid Fadelli , Tech Xplore
In recent years, engineers have been trying to devise new computers and devices that could help to solve challenging real-world problems faster and more efficiently. Some of the most promising among these are Ising machines (IMs), physics-based systems designed to tackle complex optimization problems.

Researchers at the University of California and the University of Messina have recently developed a sparse Ising machine architecture that can operate on classical and existing computer hardware. This architecture, presented in a paper published in Nature Electronics, was found to be significantly faster than standard optimization methods running on a central processing unit.

"Building domain-specific, quantum-inspired architectures has become an important area of research with the slowing down of Moore's Law," Kerem Camsari, one of the researchers who carried out the study, told TechXplore. "The primary objective of this work was to extend our earlier work on probabilistic or p-bits, conceptually in-between bits and qubits."

From transistor to memristor: Switching technologies for the future
https://techxplore.com/news/2022-06-tra ... uture.html
by King Abdullah University of Science and Technology
The invention of the transistor by Bell Laboratory in 1947 ushered in an era of electronic devices that were smaller and ran cooler using far less power than their bulky and fragile vacuum tube counterparts. Transistors function as a binary switch to facilitate electrical current from off to on states. Radios, calculators and telephones were among the first wave of instruments to replace vacuum tubes with the new semiconductor technology. As the technology scaled smaller and smaller, subsequent decades saw the steady integration of silicon transistors into devices, and today's computers, cell phones, watches, pacemakers, and virtually every kind of electronic device relies on them for high-speed processing and memory.

Enter the memristor, an electronic device that emulates the binary switch using a two- and also three-dimensional matrix configuration, or cross bar array, to regulate states of conductivity based on current resistance. Dr. Mario Lanza, KAUST associate professor of material science and engineering, asserts that, like the transistor, it's only a matter of time before memristors become the new switching technology standard, surpassing transistors in speed and operational efficiency.

Lanza is the lead author of a recently published review paper, Memristive technologies for data storage, computation, encryption, and radio-frequency communication, as part of Science magazine's coverage of the 75th anniversary of the discovery of the transistor. With contributed findings by co-authors from both industry and academia, the paper is the first to provide a comprehensive summary of data that supports memristor technology readiness level across materials and applications.

"Memristors can primarily be made from four different materials that can be applied to four applications, for a total of 16 combinations, and this paper covers them all," said Lanza. "We statistically show the technical criteria for how memristors function in these various configurations. You see what works, which is very exciting. Our compilation of findings can have an important impact on the field."

Next-Generation Data Centers Within Reach Thanks to New Energy-Efficient Switches
July 8, 2022

Introduction:
(EurekAlert) Data centers — dedicated spaces for storing, processing and disseminating data — enable everything from cloud computing to video streaming. In the process, they consume a large amount of energy transferring data back and forth inside the center. With demand for data growing exponentially, there is increasing pressure for data centers to become more energy efficient.

Data centers house servers, high-powered computers that talk to each other through interconnects, which are physical connections that allow for the exchange of data. One way to reduce energy consumption in data centers is to use light to communicate information with electrically controlled optical switches controlling the flow of light, and therefore information, between servers. These optical switches need to be multi-functional and energy-efficient to support the continued expansion of data centers.

In a paper published online July 4 in Nature Nanotechnology, a team led by University of Washington scientists reported the design of an energy-efficient, silicon-based non-volatile switch that manipulates light through the use of a phase-change material and graphene heater.

“This platform really pushes the limits of energy efficiency,” said co-corresponding author Arka Majumdar, a UW associate professor of physics and of electrical and computer engineering, as well as a faculty member at the UW Institute for Nano-Engineered Systems and the Institute for Molecular & Engineering Sciences. “Compared with what is currently being used in data centers to control photonic circuits, this technology would greatly reduce the energy needs of data centers, making them more sustainable and environmentally friendly.”

FCC chair proposes new US broadband standard of 100Mbps down, 20Mbps up

Jon Brodkin - 7/15/2022, 5:59 PM

Federal Communications Commission Chairwoman Jessica Rosenworcel is aiming to increase the agency's broadband speed standard from 25Mbps to 100Mbps on the download side and from 3Mbps to 20Mbps for uploads.

Rosenworcel's "Notice of Inquiry proposes to increase the national broadband standard to 100 megabits per second for download and 20 megabits per second for upload and discusses a range of evidence supporting this standard, including the requirements for new networks funded by the Infrastructure Investment and Jobs Act," the FCC said in an announcement today. Rosenworcel is also proposing "a separate national goal of 1Gbps/500Mbps for the future."

Researchers create key technology for quantum cryptography commercialization
https://techxplore.com/news/2022-07-key ... ation.html
by National Research Council of Science & Technology

In modern cryptosystems, users generate public and private keys that guarantee security based on computational complexity and use them to encrypt and decrypt information. Recently however, modern public-key cryptosystems have faced potential security loopholes against quantum computers with great computational power. As a solution, quantum cryptosystems have been highly noticed. They use quantum keys that guarantee security based on quantum physics rather than computational complexity; thus, they are secure even against quantum computers. Therefore, quantum cryptosystems are expected to replace modern cryptosystems.

Quantum key distribution (QKD) is the most important technology for realizing quantum cryptosystems. Two main technical issues should be addressed to commercialize QKD. One is the communication distance, and the other is the expansion from one-to-one (1:1) communication to one-to-many (1:N) or many-to-many (N:N) network communication.

Twin-field (TF) QKD, announced in 2018, is a long-distance protocol, which can dramatically increase the communication distance of QKD systems. In TF QKD, two users can distribute a key by transmitting quantum signals to an intermediate third-party that is for measurement. Given the inevitable channel loss, this architecture allows the users to increase the communication distance. However, despite its innovativeness, it has been experimentally demonstrated by only a few global QKD leading groups owing to the significant difficulty of system implementation, and research on the TF QKD network is still insufficient.

The Korea Institute of Science and Technology (KIST, Director Seok-jin Yoon) announced that their research team, the Center for Quantum Information, led by director Sang-Wook Han, succeeded in an experimental demonstration of a practical TF QKD network. This is the second experimental demonstration of the TF QKD network in the world after the University of Toronto in Canada.
