Neural RHEED alignment with limited training data during CdTe MBE growth
BartÅomiej Turowski, Jakub J. Meixner, Róża DziewiÄ tkowska +5
We introduce a data-efficient neural-vision assisted method to automate crystallographic alignment during molecular beam epitaxy (MBE) growth. Trained on reflection high-energy ele…
Spontaneous Breaking of the SU(3) Flavor Symmetry in a Quantum Hall Valley Nematic
G. Krizman, A. Kazakov, C. -W. Cho +10
Two-dimensional quantum materials can host original electronic phases that arise from the interplay of electronic correlations, symmetry and topology. In particular, the spontaneou…
Topological phase diagram and quantum magnetotransport effects in (Pb,Sn)Se quantum wells with magnetic barriers (Pb,Eu)Se
Alexander Kazakov, Valentine V. Volobuev, Chang-Woo Cho +6
In this study, we report here on a successful growth by molecular beam epitaxy of high crystalline quality PbSnSe:Bi/PbEuSe QWs with and $y =…
Temperature and Electron Concentration Dependences of 1/f Noise in HgCdTe -- Evidence for a Mobility Fluctuations Mechanism
Adil Rehman, Volodymyr Petriakov, Ivan Yahniuk +9
HgCdTe is a unique material with the band-gap tunable by the temperature, pressure, and cadmium content in a wide range, from 1.6 eV to inverted band-gap of -0.3 eV. Th…
