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
Defects activated photoluminescence in two-dimensional semiconductors: interplay between bound, charged, and free excitons
Sefaattin Tongay,Joonki Suh,Joonki Suh,Can Ataca,Wen Fan,A. V. Luce,A. V. Luce,Jeong Seuk Kang,Jonathan Liu,Changhyun Ko,Rajamani Raghunathanan,Jian Zhou,Frank Ogletree,Jingbo Li,Jeffrey C. Grossman,Junqiao Wu,Junqiao Wu,Junqiao Wu +17 more
TL;DR: This work investigates effects of anion vacancies in monolayer transition metal dichalcogenides as two-dimensional (2D) semiconductors where the vacancies density is controlled by α-particle irradiation or thermal-annealing and finds a new, sub-bandgap emission peak as well as increase in overall photoluminescence intensity as a result of the vacancy generation.
Journal ArticleDOI
Monolayer behaviour in bulk ReS2 due to electronic and vibrational decoupling
Sefaattin Tongay,Sefaattin Tongay,Hasan Sahin,Changhyun Ko,A. V. Luce,Wen Fan,Wen Fan,Kai Liu,Jian Zhou,Jian Zhou,Ying-Sheng Huang,Ching-Hwa Ho,Jinyuan Yan,D. Frank Ogletree,Shaul Aloni,Jie Ji,Shu-Shen Li,Jingbo Li,François M. Peeters,Junqiao Wu,Junqiao Wu,Junqiao Wu +21 more
TL;DR: A new member of the family ofemiconducting transition metal dichalcogenides, rhenium disulphide (ReS2), where such variation is absent and bulk behaves as electronically and vibrationally decoupled monolayers stacked together.
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
Broad-range modulation of light emission in two-dimensional semiconductors by molecular physisorption gating.
Sefaattin Tongay,Jian Zhou,Can Ataca,Jonathan Liu,Jeong Seuk Kang,Tyler S. Matthews,Long You,Jingbo Li,Jeffrey C. Grossman,Junqiao Wu,Junqiao Wu +10 more
TL;DR: Physi-sorbed O2 and/or H2O molecules electronically deplete n-type materials such as MoS2 and MoSe2, which weakens electrostatic screening that would otherwise destabilize excitons, leading to the drastic enhancement in photoluminescence.
