Tunable Direct Bandgap Optical Transitions in MoS2 Nanocrystals for Photonic Devices
TL;DR: In this paper, the size of nanocrystals could be varied within the diameter range of ∼4 to 70 nm, and a strong and tunable photoluminescence (560-518 nm) emission due to the quantum size effect of tiny NCs below a critical dimension was reported.
Journal ArticleDOI
Hydrothermal growth of few layer 2H-MoS2 for heterojunction photodetector and visible light induced photocatalytic applications
TL;DR: In this paper, a solution-processed few-layer molybdenum disulfide (MoS2) was used to synthesize a p-type silicon (p-Si)/n-MoS 2 heterostructure for visible light driven photocatalytic Rhodamine B dye degradation.
Journal ArticleDOI
Nanocrystals for silicon-based light-emitting and memory devices
TL;DR: In this paper, the size-dependent electrical and optical properties of group-IV semiconductors (Si and Ge), metal and high-k NCs for silicon planar technology compatible light-emitting and floating gate memory devices are discussed.
Journal ArticleDOI
