Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...
Topological crystals are a revolutionary class of materials that exhibit unique electronic and physical properties due to their non-trivial topological band structures. These materials have garnered ...
Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
Topological insulators are a hot topic in condensed-matter physics on account of their special properties. Electrical insulators in the bulk, these materials have surface states that conduct electrons ...
In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...
(Nanowerk Spotlight) Bismuth telluride and its alloys are unique materials. They are the best thermoelectric materials known today, and they are as important to the thermoelectric industry – for ...
An international team of researchers has found a way to determine whether a crystal is a topological insulator — and to predict crystal structures and chemical compositions in which new ones can arise ...
Researches have uncovered 'smoking-gun' evidence to confirm the workings of an emerging class of materials that could make possible 'spintronic' devices and practical quantum computers far more ...
