Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. Scientists have now found a material in which these hot electrons retain their high energy levels for much longer.
Two recent experiments to assess, for the first time, the viability of graphene for space applications. The experiments tested the material under zero-gravity conditions specifically for light propulsion and also for thermal management applications, with very encouraging results.
A high-throughput scan of possible compositions for a new class of materials known as MXenes gives researchers invaluable direction for picking the best candidate from the millions of possible material recipes.
Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believe they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer.
A new $26 million center led by the University of Notre Dame will focus on conducting research that aims to increase the performance, efficiency and capabilities of future computing systems for both commercial and defense applications.
Researchers have shown that graphene and boron nitride can be combined to create a perfect nano petri-dish. Liquid samples inside the dish can be imaged with single atom sensitivity and it is also possible to measure their elemental composition at the nanometre length scale.
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight could also pave the way for future medical diagnostics.
The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and simultaneously protects the organic semiconductor and enables the transistors to operate with unprecedented stability.
