Hi,
I am trying to solve diffusion across a boundary which only permits transport in one direction. Does anybody happen to know what boundary condition I should use?
Thanks,
Ebi
Hi;I am rather new to Comsol and I was hoping you guys could kindly help me get started!I am trying to model a silicon p-n junction to study the transient drift-diffusion after I optically excite...
