A novel superstructure in epitaxially grown 1T-TaTe
Jinwoong Hwang, Yeongrok Jin, Canxun Zhang +13
The spontaneous formation of electronic orders is a crucial element for understanding complex quantum states and engineering heterostructures in two-dimensional materials. We repor…
A plausible method of preparing the ideal p-n junction interface of a thermoelectric material by surface doping
Ji-Eun Lee, Jinwoong Hwang, Minhee Kang +10
Recent advances in two-dimensional (2D) crystals make it possible to realize an ideal interface structure that is required for device applications. Specifically, a p-n junction mad…
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides with experiment and theory
Sara Barja, Sivan Refaely-Abramson, Bruno Schuler +17
Chalcogen vacancies are considered to be the most abundant point defects in two-dimensional (2D) transition-metal dichalcogenide (TMD) semiconductors, and predicted to result in de…
Electric Field-Tuned Topological Phase Transition in Ultra-Thin Na3Bi - Towards a Topological Transistor
James L. Collins, Anton Tadich, Weikang Wu +11
The electric field induced quantum phase transition from topological to conventional insulator has been proposed as the basis of a topological field effect transistor [1-4]. In thi…
Observation of Topologically Protected States at Crystalline Phase Boundaries in Single-layer WSe2
Miguel M. Ugeda, Artem Pulkin, Shujie Tang +12
Transition metal dichalcogenide (TMD) materials are unique in the wide variety of structural and electronic phases they exhibit in the two-dimensional (2D) single-layer limit. Here…
Temperature-Dependent Electron-Electron Interaction in Graphene on SrTiO3
Hyejin Ryu, Jinwoong Hwang, Debin Wang +6
The electron band structure of graphene on SrTiO3 substrate has been investigated as a function of temperature. The high-resolution angle-resolved photoemission study reveals that…
