Discovery of Ionic Impact Ionization (I3) in Perovskites Triggered by a Single Photon
Zihan Xu, Yugang Yu, Iftikhar Ahmad Niaz +10
Organic-inorganic metal halide perovskite devices have generated significant interest for LED, photodetector, and solar cell applications due to their attractive optoelectronic pro…
Unusually large enhancement of thermopower in an electric field induced two-dimensional electron gas
Hiromichi Ohta, Taku Mizuno, Shijian Zheng +6
Two-dimensionally confined electrons showing unusually large thermopower (S) have attracted attention as a potential approach for developing high performance thermoelectric materia…
Field-induced water electrolysis switches an oxide semiconductor from an insulator to a metal
Hiromichi Ohta, Yukio Sato, Takeharu Kato +4
Here we demonstrate that water-infiltrated nanoporous glass electrically switches an oxide semiconductor from an insulator to metal. We fabricated the field effect transistor struc…
