Efficient Ohmic contacts and built-in atomic sublayer protection in MoSi2N4 and WSi2N4 monolayers


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


Tunable 2D semiconductors Researchers from the Singapore University of Technology and Design (SUTD), Hengyang Normal University, Nanjing University, National University of Singapore, and Zhejiang University identified a family of 2D semiconductors that could have lower resistance and enable further scaling. “Due to the quantum tunnelling effect, shrinking a silicon-based transistor too sm... » read more

Power/Performance Bits: Sept. 8


Backscatter radios for 5G Researchers at the Georgia Institute of Technology, Nokia Bell Labs, and Heriot-Watt University propose using backscatter radios to support high-throughput communication and 5G-speed Gb/sec data transfer using only a single transistor. “Our breakthrough is being able to communicate over 5G/millimeter-wave (mmWave) frequencies without actually having a full mmWave... » read more

2D materials–based homogeneous transistor-memory architecture for neuromorphic hardware


Abstract "In neuromorphic hardware, peripheral circuits and memories based on heterogeneous devices are generally physically separated. Thus exploring homogeneous devices for these components is an important issue for improving module integration and resistance matching. Inspired by ferroelectric proximity effect on two-dimensional materials, we present a tungsten diselenide-on-LiNbO3 cascaded... » read more

Chasing After Carbon Nanotube FETs


Carbon nanotube transistors are finally making progress for potential use in advanced logic chips after nearly a quarter century in R&D. The question now is whether they will move out of the lab and into the fab. Several government agencies, companies, foundries, and universities over the years have been developing, and are now making advancements with carbon nanotube field-effect transi... » read more

Manufacturing Bits: May 9


China’s quantum computer In its latest achievement, China has built a quantum computer. With its technology, the University of Science and Technology of China and Zhejiang University claimed to have set two records in quantum computing. In classical computing, the information is stored in bits, which can be either a “0” or “1”. In quantum computing, information is stored in quant... » read more
