[Photovoltaic] – If you want to catch more light, twist it 23 février 2020

A special class of materials known as “Weyl semimetals” have unusual physical properties. In these materials, researchers can separate electrons by their “handedness.” That’s whether the electrons’ magnetic moment is in the same direction as the electrons’ movement or the opposite direction.
This results in a host of unique phenomena that researchers can use to turn infrared light into electricity and develop very fast electronic circuits.

[Epitaxy] – Growing Highly Ordered Epitaxial Nitrides – Possible Future Applications 3 novembre 2020

Among the promising developments of nanotechnology in recent years, has been the development of the so-called bottom-up manufacturing of nanomaterials. This is the process by which materials at tiny scales and properties on the nanoscale (between 1 nm and 100 nm, or one and one hundred billionths of a meter) are manufactured through chemical growth from a material – known as epitaxy.
