Probing individual edge states with unprecedented precision

13-Sep-2018 - A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2D materials. While insulators do not conduct electrical currents, some special materials exhibit peculiar electrical ...

Seeing electrons surfing the waves of light on graphene

09-Jun-2017 - Researchers have studied how light can be used to “see” the quantum nature of an electronic material. They managed to do that by capturing light in a net of carbon atoms and slowing down light it down so that it moves almost as slow as the electrons in the graphene. Then something special ...
