Magnetotransport along a boundary: from coherent electron focusing to edge channel transport

New Journal of Physics, 2013
We study theoretically how electrons, coherently injected at one point on the boundary of a two-dimensional electron system, are focused by a perpendicular magnetic field B onto another point on the boundary.

Refined Epitaxial Growth of YbRh2Si2 Thin Films

Advanced Materials Interfaces, EarlyView.
Epitaxial thin films of the heavy fermion compound YbRh2Si2 have opened new possibilities for investigating the strange metal state. This study enhances the crystallinity and surface smoothness of YbRh2Si2 thin films grown by molecular beam epitaxy.

Integer quantum Hall effect in bilayer Dice lattices

Physical Review Research
We investigate the quantum Hall effect in bilayer dice lattices with AA-BB-CC and AB-BC-CA stacking configurations, focusing on the interplay between flat band stability and band topology.

Halide Perovskite Quantum Dots Form a Scalable Unified Platform for Resistive Memories, Crossbar Networks, Neuromorphic Synapses, and Field Effect Transistors

Advanced Materials Interfaces, EarlyView.
Halide perovskite quantum dots, with their flexible ABX3 lattice enabling collaborative electronic and ionic transport, offer scalable, low‐cost routes to resistive memories, opto‐electronic control, neuromorphic devices, and field‐effect transistors.

Quantum Hall effect and current distribution in the three-dimensional topological insulator HgTe

Physical Review Research
We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain.

Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

Advanced Materials Interfaces, EarlyView.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.
