Abstract:
In this thesis, we study the electronic transport in a single-layer zigzag Phosphorene nanoribbon by using Landauer formula and the Green's function method. In particular, we studied these nanoribbons in the presence of Rashba and Zeeman interactions. In addition, we analyzed the effects of lattice defects such as vacancies and spin interactions. In solving the quantum differential equations, we resort to computer simulation and use numerical techniques by Using the nonequilibrium Green's function method combined with the Lopez Sancho technique, the analysis of spin-dependent electron transport in mono layer zigzag Phosphorene nanoribbon (ZPNR) in a ballistic regime has been investigated. our Studies show that the spin conduction can be controlled by a controllable external magnetic field and electric field that is applied to the gate and perpendicular to the conduction channel. In particular, we have achieved the conditions that this phosphorus channel can play as a spin converter or spin filter in spintronic devices. So that the input spin up flow under certain conditions, turns out to be an output spin down flow, which is of great importance in spintronics.
