Blue phosphorus, an atomically thin synthetic semiconductor, becomes metallic as soon as it is converted into a double layer. The scientists describe the possibility of constructing nanoscale, highly efficient transistors consisting of only one element.

The results of these investigations were published as highlight article in the current issue of the journal Physical Review Letters.

The chemical element phosphorus is considered one of the most essential elements for life...

Possible pathway to fast-switching, ultra-low energy electronics based on 2D materials. Two-dimensional semiconductors offer a possible solution to the limited potential for further shrinking traditional silicon-based electronics: the long-predicted end of ‘Moore’s Law’. 2D-based electronics, which could eliminate wasted dissipation of heat and allow for very fast, ultra-low energy operation, could be enabled by a new liquidmetal deposition technique.

Moore’s law is an empirical suggestion describing that the number of transistors doubles every few years in integrated circuits (ICs)...

A team of researchers led by Sufei Shi, an assistant professor of chemical and biological engineering at Rensselaer Polytechnic Institute, has uncovered new information about the mass of individual components that make up a promising quasiparticle, known as an exciton, that could play a critical role in future applications for quantum computing, improved memory storage, and more efficient energy conversion.

Published today in Nature Communications, the team’s work brings researchers one step closer to advancing the development of semiconductor devices by deepening their understanding of an atomically thin class of materials known as transitional metal dichal...

Schematic drawing of a 2D-material-based lateral (left) and vertical (right) Schottky diode. For broad classes of 2D materials, the current-temperature relation can be universally described by a scaling exponent of 3/2 and 1, respectively, for lateral and vertical Schottky diodes.

A one-size-fits-all master equation shall pave the way towards better design of 2D material electronics. Schottky diode is composed of a metal in contact with a semiconductor. Despite its simple construction, Schottky diode is a tremendously useful component and is omnipresent in modern electronics...
