Unlocking High-Performance, Ultra-Low Power van der Waals Photo-Transistors: Toward Back-End-of-Line in-Sensor Machine Vision Applications.

Recent reports on machine learning and machine vision (MV) devices have demonstrated the potential of two-dimensional (2D) materials and devices. Yet, scalable 2D devices are being challenged by contact resistance and Fermi level pinning (FLP), power consumption, and low-cost CMOS compatible lithography processes. To enable CMOS + 2D, it is essential to find a proper lithography strategy that can fulfill these requirements.

Lattice Transformation from 2D to Quasi 1D and Phonon Properties of Exfoliated ZrS and ZrSe.

Recent reports on thermal and thermoelectric properties of emerging 2D materials have shown promising results. Among these materials are Zirconium-based chalcogenides such as zirconium disulfide (ZrS ), zirconium diselenide (ZrSe ), zirconium trisulfide (ZrS ), and zirconium triselenide (ZrSe ). Here, the thermal properties of these materials are investigated using confocal Raman spectroscopy.

Highly sensitive, scalable, and rapid SARS-CoV-2 biosensor based on InO nanoribbon transistors and phosphatase.

Unlabelled: Developing convenient and accurate SARS-CoV-2 antigen test and serology test is crucial in curbing the global COVID-19 pandemic. In this work, we report an improved indium oxide (InO) nanoribbon field-effect transistor (FET) biosensor platform detecting both SARS-CoV-2 antigen and antibody. Our FET biosensors, which were fabricated using a scalable and cost-efficient lithography-free process utilizing shadow masks, consist of an InO channel and a newly developed stable enzyme reporter.
