WorldPingMirror-image crystals reverse the direction of light-driven currents
WorldPingWhat happened
The circular photogalvanic effect (CPGE), a phenomenon that generates helicity-dependent photocurrents in noncentrosymmetric materials, can originate purely from a crystal's internal structure without a contribution from the surface, a study from Sci…
