Abstract: "Magnetism in two-dimensional (2D) van der Waals (vdW) materials has recently emerged as one of the most promising areas in condensed matter research, with many exciting emerging properties and significant potential for applications ranging from topological magnonics to low-power spintronics, quantum computing, and optical communications. In the brief time after their discovery, 2D... » read more

SOT-MRAM To Challenge SRAM
By Bryon Moyer - 13 Jan, 2022 - Comments: 1

In an era of new non-volatile memory (NVM) technologies, yet another variation is poised to join the competition — a new version of MRAM called spin-orbit torque, or SOT-MRAM. What makes this one particularly interesting is the possibility that someday it could supplant SRAM arrays in systems-on-chip (SoCs) and other integrated circuits. The key advantages of SOT-MRAM technology are the pr... » read more

Finding new materials with inverse design The Singapore-MIT Alliance for Research and Technology (SMART) has found a new way to perform general inverse design, a technique that can accelerate the discovery of new materials. The concept of inverse design is simple. Let’s say you want to develop products with select materials. In a computer, you input the desired materials and the propertie... » read more

Light-Emitting V-Pits: An Alternative Approach toward Luminescent Indium-Rich InGaN Quantum Dots
By Technical Paper Link - 21 Dec, 2021 - Comments: 0

Abstract: "Realization of fully solid-state white light emitting devices requires high efficiency blue, green, and red emitters. However, challenges remain in boosting the low quantum efficiency of long wavelength group-III-nitride light emitters through conventional quantum well growth. Here, we demonstrate a new direct metal–organic chemical vapor deposition approach to grow In-rich InGa... » read more

Efficient Ohmic contacts and built-in atomic sublayer protection in MoSi2N4 and WSi2N4 monolayers
By Technical Paper Link - 10 Dec, 2021 - Comments: 0

Abstract "Metal contacts to two-dimensional (2D) semiconductors are often plagued by the strong Fermi level pinning (FLP) effect which reduces the tunability of the Schottky barrier height (SBH) and degrades the performance of 2D semiconductor devices. Here, we show that MoSi2N4 and WSi2N4 monolayers—an emerging 2D semiconductor family with exceptional physical properties—exhibit stron... » read more

Power/Performance Bits: Dec. 6

Amplifying light for lidar Engineers at University of Texas at Austin and University of Virginia developed a light detector that can amplify weak light signals and reduce noise to improve the accuracy of lidar. "Autonomous vehicles send out laser signals that bounce off objects to tell you how far away you are. Not much light comes back, so if your detector is putting out more noise than th... » read more
