Quantum Dot Scattering in Monolayer Molybdenum Disulfide

Abstract

This chapter looks at how electrons propagate in a circular quantum dot (QD) of monolayer molybdenum disulfide (MoS2) that is exposed to an electric potential. Mathematical formulas for the eigenstates, scattering coefficients, scattering efficiency, and radial component of the reflected current and electron density are presented using the continuum model. As a function of physical characteristics such as incident electronic energy, potential barrier, and quantum dot radius, we discover two scattering regimes. We demonstrate the presence of scattering resonances for low-energy incoming electrons. We should also point out that the far-field dispersed current has unique favored scattering directions.

Thermal quantum coherence of two–qutrit Heisenberg XXZ model with Herring-Flicker coupling and Dzyaloshinskii-Moriya interaction under magnetic field

“…In addition, the Heisenberg model was used to study entanglement. However, several important works are realized in the quantum information domain, such as the isotropic Heisenberg XX model [29,30], the XXX model [31][32][33], the anisotropic Heisenberg XY model [34,35], the completely anisotropic Heisenberg XYZ model [36], as well as some new research on the spin-1/2 [37]. Unfortunately, since measurements for higher spin systems are lacking, entanglement in spin-1 systems has gotten less attention.…”
