  14. Poisson Equation Solvers

    02 Jun 2010 | | Contributor(s):: Dragica Vasileska

    There are two general schemes for solving linear systems: Direct Elimination Methods, and Iterative Methods.All the direct methods are, in some sense, based on the standard Gauss Elimination technique, which systematically applies row operations to transform the original system of equations into...

  15. Poisson Equation Solvers - General Considerations

    02 Jun 2010 | | Contributor(s):: Dragica Vasileska

    We describe the need for numerical modeling, the finite difference method, the conversion from continuous set to set of matrix equations, types of solvers for solving sparse matrix equations of the form Ax=b that result, for example, from the finite difference discretization of the Poisson...

    14 May 2009 | | Contributor(s):: Fawad Hassan

    We solve the 2-Dimensional Shrodinger-Poisson system of equations using a self consistent scheme (like Gummel Iteration). We study a double gate Silicon Mosfet oriented in the 100 direction using the above setup. We assume a simple 6-valley bandstructure for Silicon.
