	abstract = {We adapt the method developed by D.R. Penn and M. D. Stiles to implement a numerical solution to the semi-classical Boltzmann Equation on multilayer heterogeneous systems. This involves discretization of the linearized spin-independent Boltzmann Equation where the solution for each layer, considered as a bulk material, is obtained. The solutions for the different layers are then joined using boundary conditions at the interfaces to get the result for the whole multilayer structure. This method does not exploit the relaxation time approximation thus produces wider applicability especially to materials that cannot be considered to have a free-electron structure. The resulting distribution function is then used to calculate for the current density for a multi-layered material under a constant external electric field.},

	abstract = {Although the creation of spin polarization in semiconductors in a three-terminal ferromagnet-insulator-normal conductor (3T-FIN) proved successful experimentally, the behavior of spin carriers are not yet well understood. Here we develop a model based on the k{\textperiodcentered}p perturbation theory to provide an insight to the energy behavior of spin carriers in the semiconductor. A potential barrier and with a half-harmonic oscillator model was utilized. It was established that for the model potential, the spin-orbit interaction does not contribute to the additional energy in the 3T-FIN device for both polarized and unpolarized input.},

	abstract = {<div>The application of an electric field and the ensuing spin precession due to internal magnetic fields in the semiconductor of a three-terminal (3T) device is investigated using the standard diffusion theory. Because the externally applied current is confined in one direction in such a device, the effective electric field is assumed to be significant. The dominant precession direction that dictates the spin dynamics is perpendicular to both the injected spins and the electric field. At large effective electric fields, the polarization in the semiconductor is completely drawn from the polarization of the ferromagnet and becomes well-distributed in the semiconductor.</div>},
