Weyl fermions in cylindrical wires
Mikhail Erementchouk, Pinaki Mazumder
The key feature of Weyl semimetals (WSM) is the presence of topologically protected Dirac cones in a 3D material. We consider the effect of restricting geometry on the spectrum of…
Dirac electrons in the presence of matrix potential barrier: application to graphene and topological insulators
Mikhail Erementchouk, Pinaki Mazumder, M. A. Khan +1
Scattering of a 2D Dirac electrons on a rectangular matrix potential barrier is considered using the formalism of spinor transfer matrices. It is shown, in particular, that in the…
Optical signatures of states bound to vacancy defects in monolayer MoS
Mikhail Erementchouk, M. A. Khan, Michael N. Leuenberger
We show that pristine MoS single layer (SL) exhibits two bandgaps eV and eV for the optical in-plane and out-of-plane susceptibilities $χ_…
Electrical property tuning via defect engineering of single layer MoS2 by oxygen plasma
Muhammad R. Islam, Narae Kang, Udai Bhanu +5
We demonstrate that the electrical property of a single layer molybdenum disulfide (MoS2) can be significantly tuned from semiconducting to insulating regime via controlled exposur…
Effect of Monolayer Thickness Fluctuations on Coherent Exciton Coupling in Single Quantum Wells
Yuri D. Glinka, Zheng Sun, Mikhail Erementchouk +5
Monolayer fluctuations in the thickness of a semiconductor quantum well (QW) lead to three types of excitons, located in the narrower, average and thicker regions of the QW, which…
Deterministic generation of N00N states using quantum dots in a cavity
Michael N. Leuenberger, Mikhail Erementchouk
Compared to classical light sources, quantum sources based on N00N states consisting of photons achieve an -times higher phase sensitivity, giving rise to super-resolution.…
