Epitaxial Growth of Single Layer Blue Phosphorus: A New Phase of Two-Dimensional Phosphorus
Jia Lin Zhang,Songtao Zhao,Cheng Han,Zhunzhun Wang,Shu Zhong,Shuo Sun,Rui Guo,Xiong Zhou,Chengding Gu,Kai Di Yuan,Zhenyu Li,Wei Chen +11 more
TL;DR: The realization of epitaxial growth of large-scale and high quality atomic-layered blue phosphorus can enable the rapid development of novel electronic and optoelectronic devices based on this emerging two-dimensional material.
Journal ArticleDOI
Two-dimensional transition metal dichalcogenides: interface and defect engineering
TL;DR: Two-dimensional transition metal dichalcogenides (TMDCs) have been considered as promising candidates for next generation nanoelectronics and their corresponding applications in electronic and optoelectronic devices.
Journal ArticleDOI
Surface transfer doping induced effective modulation on ambipolar characteristics of few-layer black phosphorus
Du Xiang,Cheng Han,Jing Wu,Shu Zhong,Yiyang Liu,Jiadan Lin,Xueao Zhang,Wenping Hu,Barbaros Özyilmaz,A. H. Castro Neto,Andrew T. S. Wee,Wei Chen +11 more
TL;DR: An effective modulation on ambipolar characteristics of few-layer black phosphorus transistors through in situ surface functionalization with caesium carbonate and molybdenum trioxide is reported, indicating a greatly improved electron-transport behaviour.
Journal ArticleDOI
Electron-Doping-Enhanced Trion Formation in Monolayer Molybdenum Disulfide Functionalized with Cesium Carbonate
Jiadan Lin,Jiadan Lin,Cheng Han,Cheng Han,Fei Wang,Fei Wang,Rui Wang,Du Xiang,Shiqiao Qin,Xueao Zhang,Li Wang,Hua Zhang,Andrew T. S. Wee,Wei Chen +13 more
TL;DR: The electron doping enhances the formation of negative trions in monolayer MoS2 under light irradiation and significantly reduces the charge recombination of photoexcited electron-hole pairs, which results in large photoluminescence suppression and an obvious photocurrent enhancement in MonS2 FETs.

TL;DR: It is demonstrated for the first time that black phosphorus can be configured as an excellent UV photodetector with a specific detectivity ∼3 × 10(13) Jones and found that the UV photoresponsivity can be significantly enhanced to ∼9 × 10 A W(-1) by applying a source-drain bias (VSD) of 3 V, which is the highest ever measured in any 2D material.
