Doping against the native propensity of MoS2: degenerate hole doping by cation substitution.
Joonki Suh,Tae Eon Park,Der Yuh Lin,Deyi Fu,Joonsuk Park,Hee Joon Jung,Yabin Chen,Changhyun Ko,Chaun Jang,Yinghui Sun,Robert Sinclair,Joonyeon Chang,Sefaattin Tongay,Junqiao Wu,Junqiao Wu +14 more
TL;DR: Stable p-type conduction in MoS2 is demonstrated by substitutional niobium (Nb) doping, leading to a degenerate hole density of ∼ 3 × 10(19) cm(-3), and it is expected that the synthesis technique demonstrated here can be generally extended to other TMDs for doping against their native unipolar propensity.

Kai Liu,Qimin Yan,Michelle Chen,Wen Fan,Wen Fan,Yinghui Sun,Joonki Suh,Deyi Fu,Sangwook Lee,Jian Zhou,Sefaattin Tongay,Jie Ji,Jeffrey B. Neaton,Junqiao Wu +13 more
TL;DR: In this article, the 2D elastic modulus of CVD monolayer MoS2 and WS2 was investigated and it was shown that the moduli of their bilayer heterostructures are comparable to the corresponding bilayer homostructure, implying similar interactions between the hetero monolayers as between homo monlayers.

TL;DR: High 2D elastic moduli of CVD monolayer MoS2 and WS2 (∼170 N/m) are reported, which is very close to the value of exfoliated MoS1 andWS2 monolayers and almost half thevalue of the strongest material, graphene.

TL;DR: The mechanism of a newly observed photovoltaic effect which occurs in ferroelectrics with periodic domain structures, found in BiFeO(3) films, is elucidated and should occur in any system with a similar periodic potential.
Chemical Vapor Deposition of Large-Size Monolayer MoSe2 Crystals on Molten Glass.
J. C. Chen,Xiaoxu Zhao,Sherman Jun Rong Tan,Hai Xu,Bo Wu,Bo Liu,Bo Liu,Deyi Fu,Wei Fu,Dechao Geng,Yanpeng Liu,Wei Liu,Wei Tang,Linjun Li,Wu Zhou,Wu Zhou,Tze Chien Sum,Kian Ping Loh +17 more
TL;DR: The results demonstrate that "liquid-state" glass is a highly promising substrate for the low-cost growth of high-quality large-size 2D transition metal dichalcogenides (TMDs).
