Poisson Equation

  1. May 6, 2009 #1
    Hi

    I am working with MOSFETs and in this context I am trying to solve poissons equation inside a MOSFET. Only in the direction from the gate through the oxide and into the silicon. I know the analytic solution but now I want solve Poissons equation with the use of finite difference.

    When I found the analytic solution, I utilized that the potential and the derivative of the potential is zero deep into the body.

    When I make the finite difference scheme, how do I ensure that the potential and the derivative of the potential is zero deep into the silicon?

    Thanks in advance
