Journal ArticleDOI
Band offsets and heterostructures of two-dimensional semiconductors
TL;DR: In this paper, the band offsets and heterostructures of monolayer and few-layer transition-metal dichalcogenides MX2 (M = Mo, W; X = S, Se, Te) are investigated from first principles calculations.
Journal ArticleDOI
High Defect Tolerance in Lead Halide Perovskite CsPbBr3
Jun Kang,Lin-Wang Wang +1 more
TL;DR: Interestingly, CsPbBr3 is found to be highly defect-tolerant in terms of its electronic structure, which can maintain its good electronic quality despite the presence of defects.
Journal ArticleDOI
Tuning Interlayer Coupling in Large-Area Heterostructures with CVD-Grown MoS2 and WS2 Monolayers
Sefaattin Tongay,Wen Fan,Wen Fan,Jun Kang,Joonsuk Park,Unsal Koldemir,Joonki Suh,Deepa S. Narang,Kai Liu,Jie Ji,Jingbo Li,Robert Sinclair,Junqiao Wu,Junqiao Wu,Junqiao Wu +14 more
TL;DR: This work demonstrates large-area (>tens of micrometers) heterostructures of CVD-grown WS2 and MoS2 monolayers, where the interlayer interaction is externally tuned from noncoupling to strong coupling, which opens up venues to creating new material systems with rich functionalities and novel physical effects.
Journal ArticleDOI
Design Principles for Trap-Free CsPbX3 Nanocrystals: Enumerating and Eliminating Surface Halide Vacancies with Softer Lewis Bases.
David P. Nenon,Kimo Pressler,Jun Kang,Brent A. Koscher,Jacob H. Olshansky,Wojciech T. Osowiecki,Matthew A. Koc,Lin-Wang Wang,A. Paul Alivisatos +8 more
TL;DR: This work provides a systematic framework for preparing highly luminescent CsPbX3 nanocrystals with variable compositions and dimensionalities, thereby improving the fundamental understanding of these materials and informing future synthetic and post-synthetic efforts toward trap-free CspbX2 nanocrystal efforts.
Journal ArticleDOI
Novel and Enhanced Optoelectronic Performances of Multilayer MoS2-WS2 Heterostructure Transistors
TL;DR: In this article, the multilayer van der Waals heterostructures with different configurations are reported and their optoelectronic properties are studied and shown to possess new functionalities and superior electrical and optical properties that far exceed the one for their constituents, MoS2 or WS2.
