The following equation describe the current densities of electrons and holes in a semiconductor.
The variables are J_n, J_p, n, p and E.
rho is charge density which is equal to .
G and R are function of generation and recombination.
I would like to change it into a weak form and use the pde interface . However, I do not know how to convert (3) and (5) into weak forms. Any suggestion to convert them? Thanks.
