Phonon-pump electronic-probe study of methylammonium lead iodide reveals electronically decoupled organic and inorganic sublattices
Peijun Guo, Arun Mannodi-Kanakkithodi, Jue Gong +10
Organic-inorganic hybrid perovskites such as methylammonium lead iodide (CH3NH3PbI3) are game-changing semiconductors for solar cells and light-emitting devices owing to their exce…
Defect Engineering for Modulating the Trap States in Two-dimensional Photoconductor
Jie Jiang, Chongyi Ling, Tao Xu +10
Defect induced trap states are essential in determining the performance of semiconductor photodetectors. The de-trap time of carriers from a deep trap could be prolonged by several…
