Journal ArticleDOI
2D materials advances: From large scale synthesis and controlled heterostructures to improved characterization techniques, defects and applications
Zhong Lin,Amber McCreary,Natalie Briggs,Shruti Subramanian,Kehao Zhang,Yifan Sun,Xufan Li,Nicholas J. Borys,Hongtao Yuan,Susan K. Fullerton-Shirey,Alexey Chernikov,Alexey Chernikov,Hui Zhao,Stephen McDonnell,Aaron M. Lindenberg,Kai Xiao,Brian J. Le Roy,Marija Drndic,James C. M. Hwang,Jiwoong Park,Manish Chhowalla,Raymond E. Schaak,Ali Javey,Ali Javey,Mark C. Hersam,Joshua A. Robinson,Mauricio Terrones +26 more
TL;DR: Lin et al. as mentioned in this paper reviewed the most recent breakthrough discoveries as well as emerging opportunities and remaining challenges in the field of 2D materials, including transition metal dichalcogenides, mono-elemental 2D sheets, and several carbide-and nitride-based materials.
Journal ArticleDOI
Manganese Doping of Monolayer MoS2: The Substrate Is Critical
Kehao Zhang,Simin Feng,Junjie Wang,Angelica Azcatl,Ning Lu,Rafik Addou,Nan Wang,Chanjing Zhou,Jordan O. Lerach,Vincent Bojan,Moon J. Kim,Long Qing Chen,Robert M. Wallace,Mauricio Terrones,Jun Zhu,Joshua A. Robinson +15 more
TL;DR: It is shown that inert substrates (i.e., graphene) permit the incorporation of several percent Mn in MoS2, while substrates with reactive surface terminations preclude Mn incorporation and merely lead to defective MoS 2.

Vertical 2D/3D Semiconductor Heterostructures Based on Epitaxial Molybdenum Disulfide and Gallium Nitride.
Dmitry Ruzmetov,Dmitry Ruzmetov,Kehao Zhang,Gheorghe Stan,Berc Kalanyan,Ganesh R. Bhimanapati,Sarah M. Eichfeld,Robert A. Burke,Pankaj B. Shah,Terrance O'Regan,Frank J. Crowne,A. Glen Birdwell,Joshua A. Robinson,Albert V. Davydov,Tony Ivanov +14 more
TL;DR: Lattice-matched epitaxial growth of molybdenum disulfide (MoS2) directly on gallium nitride (GaN), resulting in high-quality, unstrained, single-layer MoS2 with strict registry to the GaN lattice presents a promising path toward the implementation of high-performance electronic devices based on 2D/3D vertical heterostructures.
Journal ArticleDOI
Realizing Large-Scale, Electronic-Grade Two-Dimensional Semiconductors
Yu-Chuan Lin,Bhakti Jariwala,Brian M. Bersch,Ke Xu,Yifan Nie,Baoming Wang,Sarah M. Eichfeld,Xiaotian Zhang,Tanushree H. Choudhury,Yi Pan,Rafik Addou,Christopher M. Smyth,Jun Li,Kehao Zhang,M. Aman Haque,Stefan Fölsch,Randall M. Feenstra,Robert M. Wallace,Kyeongjae Cho,Susan K. Fullerton-Shirey,Joan M. Redwing,Joshua A. Robinson +21 more
TL;DR: This work establishes that realization of electronic-grade epitaxial TMDs must consider the impact of the TMD precursors, substrate, and the 2D/3D interface as leading factors in electronic performance.
