Monte Carlo Simulation of Spin Relaxation in Nanowires and 2-D Channels of Ii–vi Semiconductors

We have analyzed the spin transport behaviour of four II-VI semiconductor nanowires by simulating spin polarized transport using a semi-classical Monte-Carlo approach. The different scattering mechanisms considered are acoustic phonon scattering, surface roughness scattering, polar optical phonon scattering, and spin flip scattering. The II-VI materials used in our study are CdS, CdSe, ZnO and ZnS. The spin transport behaviour is first studied by varying the temperature (4-500 K) at a fixed diameter of 10 nm and also by varying the diameter (8-12 nm) at a fixed temperature of 300 K. For II-VI compounds, the dominant mechanism is for spin relaxation; D'yakonovPerel and Elliot Yafet have been actively employed in the first order model to simulate the spin transport. The dependence of the spin relaxation length (SRL) on the diameter and temperature has been analyzed.

The full potential linearized augmented plane wave method within the framework of density functional theory (DFT) is employed to investigate the structural, magnetic, electronic and optical properties of Ti -doped ZnTe and CdTe in the zinc blende phase. In this approach the local spin density approximation (LSDA) is used for the exchange-correlation (XC) potential. Results are provided for the lattice constant, bulk modulus, pressure derivative, magnetic moment, band structure, density of states and refractive indices. Our results are compared with other theoretical works and good agreement is shown.
