Starchy nanocomposite films Researchers from Queen Mary University of London created biodegradable, flexible, and electrically conductive nanocomposite films made using potato starch instead of petroleum-based materials. The starch-based films decompose within a month when buried in soil. In addition to starch, the nanocomposite films contain the conductive 2D material MXene. Adjusting the ... » read more

Flexible, low power phase-change memory Engineers at Stanford University created a flexible phase-change memory. The non-volatile phase-change memory device is made up of germanium, antimony, and tellurium (GST) between two metal electrodes. 1s and 0s represent measurements of electrical resistance in the GST material. “A typical phase-change memory device can store two states of resis... » read more

MXene-GaN van der Waals metal-semiconductor junctions for high performance multiple quantum well photodetectors
By Technical Paper Link - 12 Oct, 2021 - Comments: 0

Abstract: "A MXene-GaN-MXene based multiple quantum well photodetector was prepared on patterned sapphire substrate by facile drop casting. The use of MXene electrodes improves the responsivity and reduces dark current, compared with traditional Metal-Semiconductor-Metal (MSM) photodetectors using Cr/Au electrodes. Dark current of the device using MXene-GaN van der Waals junctions is reduced b... » read more

MRAM speed Researchers at ETH Zurich and Imec investigated exactly how quickly magnetoresistive RAM (MRAM) can store data. In the team's MRAM, electrons with opposite spin directions are spatially separated by the spin-orbit interaction, creating an effective magnetic field that can be used to invert the direction of magnetization of a tiny metal dot. "We know from earlier experiments, i... » read more

Conductive yarn Researchers at Drexel University created an electrically conductive coating for yarn that withstands wearing, washing, and industrial textile manufacturing. Rather than using metallic fibers, the coating is made up of different sized flakes of the two-dimensional material MXene, which was applied to standard cellulose-based yarns. Titanium carbide MXene can be produced in f... » read more
