I want to know whether the basic semiconductor equations can be solved by mathematical PDE interface in Comsol. The equations that I want to solve are:
1). -∇^2 V=q/epsilon*(p-n+Nd-Na)
2). ∇.[p*μ_p*∇V+Dp*∇p]=(p-peq)/taup
3). ∇.[n*μ_n*∇V+Dn*∇n]=(n-neq)/taun
where V, p and n are the dependent variables for which the equations are to be solved. Where as q and epsilon are constants. Nd,Na are doping concentrations.
To solve these equations which PDE interface, coefficient form or general form should be used.
I know that Comsol has semiconductor module to simulate semiconductor devices, but as part of my project work, I need to work on PDE solvers on semiconductor equations.
Thanks a lot.
