    Gummel method solving the n-type semiconductor(Poisson equation)

    Thanks for your reply and sorry for my late answer :). I would like to ask about which device you are writing a model. Because I am writing about pn junction (time-independent dn/dt=dp/dt=0) and my programme shows just a little convergence when bias voltage is applied. I need an advice. Thanks!

    Gummel method solving the n-type semiconductor(Poisson equation)

    Hello, I am trying to simulate n-type Silicon using the Gummel method (decoupled method). Here is the link where I stuck http://courses.engr.illinois.edu/ece539/Notes/ch2.pdf . There is (37) formula in the text and I cannot figure out where I need to get V(i-1) and V(i+1) terms on the right...
