Gate-induced insulator to band-like transport transition in organolead halide perovskite
Dehui Li, Hung-Chieh Cheng, Hao Wu +5
Understanding the intrinsic charge transport in organolead halide perovskites is essential for the development of high-efficiency photovoltaics and other optoelectronic devices. De…
Wafer-scale growth of large arrays of perovskite microplate crystals for functional electronics and optoelectronics
Gongming Wang, Dehui Li, Hung-Chieh Cheng +11
Methylammonium lead iodide perovskite has attracted intensive interest for its diverse optoelectronic applications. However, most studies to date have been limited to bulk thin fil…
Van der Waals heterojunction devices based on organohalide perovskites and two-dimensional materials
Hung-Chieh Cheng, Gongming Wang, Dehui Li +7
The recently emerged organohalide perovskites (e.g., CH3NH3PbI3) have drawn intense attention for high efficiency solar cells. However, with a considerable solubility in many solve…
Towards barrier free contact to MoS2 using graphene electrodes
Yuan Liu, Hao Wu, Hung Chieh Cheng +9
The two-dimensional (2D) layered semiconductors such as MoS2 have attracted tremendous interest as a new class of electronic materials. However, there is considerable challenge in…
