TL;DR: An important advance in the development of layered semiconductor heterostructures, an essential step towards achieving functional electronics and optoelectronics.
Journal ArticleDOI
Growth of Alloy MoS2xSe2(1–x) Nanosheets with Fully Tunable Chemical Compositions and Optical Properties
Honglai Li,Xidong Duan,Xueping Wu,Xiujuan Zhuang,Hong Zhou,Qinglin Zhang,Xiaoli Zhu,Wei Hu,Pinyun Ren,Pengfei Guo,Liang Ma,Xiaopeng Fan,Xiaoxia Wang,Jinyou Xu,Anlian Pan,Xiangfeng Duan +15 more
TL;DR: A simple one-step chemical vapor deposition approach is reported for the simultaneous growth of alloy MoS2xSe2(1-x) triangular nanosheets with complete composition tunability and both the Raman and the photoluminescence studies show tunable optical properties consistent with composition of the alloy nanOSheets.
Journal ArticleDOI
Synthesis of WS2xSe2–2x Alloy Nanosheets with Composition-Tunable Electronic Properties
Xidong Duan,Chen Wang,Zheng Fan,Guolin Hao,Liangzhi Kou,Udayabagya Halim,Honglai Li,Xueping Wu,Yicheng Wang,Jian-Hui Jiang,Anlian Pan,Yu Huang,Ruqin Yu,Xiangfeng Duan +13 more
TL;DR: A systematic control of the electronic properties of 2D-TMDs is demonstrated by creating mixed alloys of the intrinsically p-type WSe2 and intrinsically n-type WS2 with variable alloy compositions and it is shown that a series of WS2xSe2-2x alloy nanosheets can be synthesized with fully tunable chemical compositions and optical properties.
