Journal ArticleDOI
Highly Crystalline CVD-grown Multilayer MoSe2 Thin Film Transistor for Fast Photodetector
Chulseung Jung,Seung Min Kim,Hyunseong Moon,Gyuchull Han,Junyeon Kwon,Yun Kyoung Hong,I. Omkaram,Youngbok Yoon,Sunkook Kim,Jongjin Park +9 more
TL;DR: CVD-grown multilayer MoSe2 thin-film transistors (TFTs) show p-type-dominant ambipolar behaviors, which are attributed to the formation of Se vacancies generated at the decomposition temperature after the CVD growth for 10 min.
Journal ArticleDOI
Giant Photoamplification in Indirect‐Bandgap Multilayer MoS2 Phototransistors with Local Bottom‐Gate Structures
TL;DR: Simulation results suggest that high photoresponsivity can be achieved in indirect-bandgap multilayer MoS2 phototransistors by optimizing the optoelectronic design.
Journal ArticleDOI
High-Mobility Transistors Based on Large-Area and Highly Crystalline CVD-Grown MoSe2 Films on Insulating Substrates.
Jong-Soo Rhyee,Junyeon Kwon,Piyush Dak,Jin Hee Kim,Seung Min Kim,Jozeph Park,Young Ki Hong,Won Geun Song,I. Omkaram,Muhammad A. Alam,Sunkook Kim +10 more
TL;DR: Large-area and highly crystalline CVD-grown multilayer MoSe2 films exhibit a well-defined crystal structure (2H phase) and large grains reaching several hundred micrometers and suggest that high mobility materials will be indispensable for various future applications such as high-resolution displays and human-centric soft electronics.
Journal ArticleDOI
