Evidences for the exciton gas phase and its condensation in monolayer 1T-ZrTe2
Yekai Song, Chunjing Jia, Hongyu Xiong +15
The excitonic insulator (EI) is a Bose-Einstein condensation (BEC) of excitons bound by electron-hole interaction in a solid, which could support high-temperature BEC transition. T…
Electronic bandstructure of in-plane ferroelectric van der Waals
James L. Collins, Chutian Wang, Anton Tadich +11
Layered indium selenides () have recently been discovered to host robust out-of-plane and in-plane ferroelectricity in the and ' phases, respectively. In this…
Epitaxial growth and characterization of high quality Bi2O2Se thin films on SrTiO3 substrates by pulsed laser deposition
Yekai Song, Zhuojun Li, Hui Li +8
Recently, Bi2O2Se is discovered as a promising two-dimensional (2D) semiconductor for next generation electronics, due to its moderate bandgap size, high electron mobility and pron…
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…
Edge Control of Graphene Domains Grown on Hexagonal Boron Nitride
Lingxiu Chen, Haomin Wang, Shujie Tang +8
Edge structure of graphene has a significant influence on its electronic properties. However, control over the edge structure of graphene domains on insulating substrates is still…
