Researchers with the School of Electrical Engineering at KAIST have developed a new approach to the underlying physics of semiconductors. They calculated the quasi-Fermi levels in molecular junctions applying an initio approach.
University of Arizona researchers report a discovery that opens new possibilities in the development of spintronics, a new type of memory storage capable of processing information much faster than current technology while consuming less energy.
An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices.
A team of researchers co-led by Berkeley Lab has observed unusually long-lived wavelike electrons called 'plasmons' in a new class of electronically conducting material. Plasmons are very important for determining the optical and electronic properties of metals for the development of new sensors and communication devices.
Experts from the University of Surrey believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and deliver electricity at high power rates, particularly for mobile applications.
In 2005, Science asked if it was possible to develop a magnetic semiconductor that could work at room temperature. Now, just fifteen years later, researchers at Stevens Institute of Technology have developed those materials in two-dimensional form, solving one of science's most intractable problems.
NRL researchers have developed a new resonant tunneling diode (RTD) with performance beyond the anticipated speed of 5G.
Memristive devices behave similarly to neurons in the brain. Researchers from the Jülich Aachen Research Alliance (JARA) and the technology group Heraeus have now discovered how to systematically control the functional behaviour of these elements. The smallest differences in material composition are found crucial: differences so small that until now experts had failed to notice them.
Russian scientists have conducted a theoretical study of the effects of defects in graphene on electron transfer at the graphene-solution interface. Their calculations show that defects can increase the charge transfer rate by an order of magnitude. Moreover, by varying the type of defect, it is possible to selectively catalyze the electron transfer to a certain class of reagents in solution.
Prof. ZHONG Zhicheng's team at the Ningbo Institute of Materials Technology and Engineering has investigated the electronic structure of the recently discovered nickelate superconductors NdNiO2. They successfully explained the experimental difficulties in synthesizing superconducting nickelates, in cooperation with Prof. Karsten Held at Vienna University of Technology.
