Two Types of 3D Quantum Hall Effects in Multilayer WTe
Xurui Zhang, Yeonghun Lee, Vivek Kakani +3
Interplay between the topological surface states and bulk states gives rise to diverse exotic transport phenomena in topological materials. The recently proposed Weyl orbit in topo…
A Nanometer-Thick Oxide Semiconductor Transistor with Ultra-High Drain Current
Zehao Lin, Mengwei Si, Vahid Askarpour +12
High drive current is a critical performance parameter in semiconductor devices for high-speed, low-power logic applications or high-efficiency, high-power, high-speed radio freque…
Why In2O3 Can Make 0.7 nm Atomic Layer Thin Transistors?
Mengwei Si, Yaoqiao Hu, Zehao Lin +7
In this work, we demonstrate enhancement-mode field-effect transistors by atomic-layer-deposited (ALD) amorphous In2O3 channel with thickness down to 0.7 nm. Thickness is found to…
Flatbands and Mechanical Deformation Effects in the Moiré Superlattice of MoS-WSe Heterobilayers
Dacen Waters, Yifan Nie, Felix Lüpke +11
It has recently been shown that quantum-confined states can appear in epitaxially grown van der Waals material heterobilayers without a rotational misalignment (), assoc…
Real-time ab initio simulation of inelastic electron scattering using the exact, density functional, and alternative approaches
Yeonghun Lee, Xiaolong Yao, Massimo V. Fischetti +1
To investigate inelastic electron scattering, which is ubiquitous in various fields of study, we carry out ab initio study of the real-time dynamics of a one-dimensional electron w…
First-principles study of metal-graphene edge contact for ballistic Josephson junction
Yeonghun Lee, Jeongwoon Hwang, Fan Zhang +1
Edge-contacted superconductor-graphene-superconductor Josephson junction have been utilized to realize topological superconductivity, which have shown superconducting signatures in…
