Assisistant Professor Hiroyuki Yoshida demonstrated, for the first time, that the unoccupied states of solid materials can be precisely examined by detecting the near-ultraviolet light following the ...
The rapid development of two-dimensional quantum materials, such as twisted bilayer graphene, monolayer copper superconductors, and quantum spin Hall materials, has demonstrated both important ...
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's ...
