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…
Electric field induced strong enhancement of electroluminescence in multi-Layer MoS2
Dehui Li, Rui Cheng, Hailong Zhou +6
The layered transition metal dichalcogenides (TMDs) have attracted considerable interest due to their unique electronic and optical properties. Here we report electric field induce…
Electroluminescence and photocurrent generation from atomically sharp WSe2/MoS2 heterojunction p-n diodes
Rui Cheng, Dehui Li, Hailong Zhou +7
The p-n diodes represent the most fundamental device building block for diverse optoelectronic functions, but are difficult to achieve in atomically thin transition metal dichalcog…
