Missing link between new topological phases of matter discovered

Nanowerk.com - 17 октября, 2017 - 16:47
Physicists investigated a class of materials that exhibit characteristics of topological insulators. During these studies they discovered a transition between two different topological phases, one of which is ferroelectric, meaning a phase in the material that exhibits spontaneous electric polarisation and can be reversed by an external electric field.

Chemical treatment improves quantum dot lasers

ScienceDaily.com: Nanotechnology News - 16 октября, 2017 - 20:26
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.
