TL;DR: In this paper, the authors measured the conduction and valance band offsets at the interface between two two-dimensional materials: molybdenum disulphide and tungsten diselenide.
Journal ArticleDOI
Ultrafast generation of pseudo-magnetic field for valley excitons in wse2 monolayers
Jonghwan Kim,Xiaoping Hong,Chenhao Jin,Su-Fei Shi,Chih Yuan S. Chang,Ming-Hui Chiu,Lain-Jong Li,Feng Wang,Feng Wang +8 more
TL;DR: It is demonstrated that an ultrafast and ultrahigh valley pseudo-magnetic field can be generated by using circularly polarized femtosecond pulses to selectively control the valley degree of freedom in monolayer MX2.
Journal ArticleDOI
Atomically thin heterostructures based on single-layer tungsten diselenide and graphene.
Yu-Chuan Lin,Chih Yuan S. Chang,Ram Krishna Ghosh,Jie Li,Hui Zhu,Rafik Addou,Bogdan Diaconescu,Taisuke Ohta,Xin Peng,Ning Lu,Moon J. Kim,Jeremy T. Robinson,Robert M. Wallace,Theresa S. Mayer,Suman Datta,Lain-Jong Li,Joshua A. Robinson +16 more
TL;DR: The direct growth of crystalline, monolayer tungsten diselenide (WSe2) on epitaxial graphene (EG) grown from silicon carbide is reported, providing evidence that an additional barrier to carrier transport beyond the expected WSe2/EG band offset exists due to the interlayer gap.

Determination of band alignment in transition metal dichalcogenides heterojunctions
Ming-Hui Chiu,Chendong Zhang,Hung-Wei Shiu,Chih-Piao Chuu,Chang-Hsiao Chen,Chih Yuan S. Chang,Chia-Hao Chen,Mei-Yin Chou,Chih-Kang Shih,Lain-Jong Li +9 more
TL;DR: In this paper, the authors determined a type-II alignment between transition metal dichalcogenides (TMDs) as 2D electronic materials using microbeam X-ray photoelectron spectroscopy ({\mu}-XPS) and scanning tunneling microscopy/spectroscopy(STM/S).
