Hello, I'm new with COMSOL. I'd like to know what is the most suitable module or procedure to study the electric field in air between a metal probe and a semiconductor. I understand that "Electrostatics Module" only works with metals or dielectrics, so it is not valid. But the "Semiconductor Module" apparently works just with semiconductors (so gap, density of states, carrier mobilities... are properties to be due in each domain). How can I do to solve electric fields outside de semiconducting layers, namely air? Thanks a lot!
