MATLAB Dont know how to write PDE of semiconductors in Matlab (PDE solver)

  1. Mar 24, 2012 #1
    Hey! I am still stuck on solving pn junction using Matlab. Firstly, I tried to write my own program to calculate all variables (using Gummel approximation and similar stuff) and indeed I did it, but unfortunately my program is tend to diverge. So I decided to use PDE solver which is included in Matlab. However, I dont know how to write semiconductors equations according to PDE syntax. Please help me or give an advise at least.
    Semiconductor equations are here: http://journals.tubitak.gov.tr/elektrik/issues/elk-11-19-1/elk-19-1-7-0812-29.pdf - 2,3,4,5,6 eq.
    I am trying to use this tutorial: http://www.mathworks.se/help/techdoc/math/f1-663004.html#brfhed9-1 [Broken]
