Odd-integer quantum Hall states and giant spin susceptibility in p-type few-layer WSe2
Shuigang Xu, Junying Shen, Gen Long +17
We fabricate high-mobility p-type few-layer WSe2 field-effect transistors and surprisingly observe a series of quantum Hall (QH) states following an unconventional sequence predomi…
Band bending at interfaces between topological insulator Bi2Se3 and transition metals
Weiguang Ye, A. B. Pakhomov, Shuigang Xu +11
Interfaces between exfoliated topological insulator Bi2Se3 and several transition metals deposited by sputtering were studied by XPS, SIMS, UPS and contact I-V measurements. Chemic…
Observation of Valley Zeeman and Quantum Hall Effects at Q Valley of Few-Layer Transition Metal Disulfides
Zefei Wu, Shuigang Xu, Huanhuan Lu +10
In few-layer (FL) transition metal dichalcogenides (TMDC), the conduction bands along the Gamma-K directions shift downward energetically in the presence of interlayer interactions…
Fast Transfer-free Synthesis of High-quality Monolayer Graphene on Insulating Substrates by Simple Rapid Thermal Treatment
Zefei Wu, Yanqing Guo, Yuzheng Guo +13
The transfer-free synthesis of high-quality, large-area graphene on a given dielectric substrate, which is highly desirable for device applications, remains a significant challenge…
Universal low-temperature Ohmic contacts for quantum transport in transition metal dichalcogenides
Shuigang Xu, Zefei Wu, Huanhuan Lu +14
Low carrier mobility and high electrical contact resistance are two major obstacles prohibiting explorations of quantum transport in TMDCs. Here, we demonstrate an effective method…
Detection of Interlayer Interaction in Few-layer Graphene through Landau Level Spectroscopy
Zefei Wu, Yu Han, Wei Zhu +12
We demonstrate that surface relaxation, which is insignificant in trilayer graphene, starts to manifest in Bernal-stacked tetralayer graphene. Bernal-stacked few-layer graphene has…
