Miniaturized Liquid Metal-based Flexible Electrochemical Detection System on Fabric


Researchers from Beihang University (Beijing), Zhejiang University, and Tsinghua University. Abstract "Integrated electrochemical sensing platforms in wearable devices have great prospects in biomedical applications. However, traditional electrochemical platforms are generally fabricated on airtight printed circuit boards, which lack sufficient flexibility, air permeability, and conformab... » read more

Silicon Thermo-Optic Switches with Graphene Heaters Operating at Mid-Infrared Waveband


Abstract "The mid-infrared (MIR, 2–20 μm) waveband is of great interest for integrated photonics in many applications such as on-chip spectroscopic chemical sensing, and optical communication. Thermo-optic switches are essential to large-scale integrated photonic circuits at MIR wavebands. However, current technologies require a thick cladding layer, high driving voltages or may introduce h... » read more

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
