Extreme sensitivity of graphene photoconductivity to environmental gases
Callum J. Docherty, Cheng-Te Lin, Hannah J. Joyce +4
Graphene is a single layer of covalently bonded carbon atoms, which was discovered only 8 years ago and yet has already attracted intense research and commercial interest. Initial…
Integrated Circuits Based on Bilayer MoS2 Transistors
Han Wang, Lili Yu, Yi-Hsien Lee +7
Two-dimensional (2D) materials, such as molybdenum disulfide (MoS2), have been shown to exhibit excellent electrical and optical properties. The semiconducting nature of MoS2 allow…
Synthesis of Large-Area MoS2 Atomic Layers with Chemical Vapor Deposition
Yi-Hsien Lee, Xin-Quan Zhang, Wenjing Zhang +8
Large-area MoS2 atomic layers are synthesized on SiO2 substrates by chemical vapor deposition using MoO3 and S powders as the reactants. Optical, microscopic and electrical measure…
Growth of Large-Area and Highly Crystalline MoS2 Thin Layers on Insulating Substrates
Keng-Ku Liu, Wenjing Zhang, Yi-Hsien Lee +9
The two-dimensional layer of molybdenum disulfide (MoS2) has recently attracted much interest due to its direct-gap property and potential applications in optoelectronics and energ…
