What Determinates the Magnetoelectric and Magnetotransport Properties of Nanoscale Heterostructures?(1/3)

Project Details

Description

Recently, many experimental techniques and theoretical models have been devoted to develope novel spintronics device, and the “interfacial magnetoelectric” effect is one of the vital issues to dominate the charge-, spin-, and magneto-transport properties in nmscale hetoerostructures. In this project, our self-developed “JunPy” package combines (1) first-principles calculation with noncollinear spin-orbit coupling, external bias, mechanical strain, magnetic field, gate voltage, and ferroelectric control with (2) non-equilibrium Green’s function (NEGF) method and generalized tight-binding model to provide both numerical simulation and analytical analysis for (a) multi-functional modulation spin transport in TMD nanoribbon based heterostructures, (b) out-of-plane current driven spin-transfer torque and voltage-controlled magnetic anisotropy torque in trilayer system, and (c) in-plane current driven spin-orbit torque in FM/HF bilayer system. We believe this multi-discipline and highly challenging work, involving computer programming, analytical derivation, and first-principles calculation, may provide promising simulation tools for next-generation, multifunctional and low-energy consumption spintronics devices.
