Dear all,
I am trying to simulate a structure which consists of different material layers. I would like to see Electric field and Electric Potential distributions of a certain potential applied to the boundaries of substrate (poly-Si). My multilayer structure includes two different metall layers. When I press compute, Comsol asks me to enter Relative Permittivity values for these metals, which is actually incorrect. I set them to 0.01 but also set all boundaries of metal layers to 0V potential. Is this approach is correct?
After computing Electric Potentials (image is attached), instead of V I type sqrt(es.Ex*es.Ex+es.Ey*es.Ey+es.Ez*es.Ez) in Expression field to get Electric Field distribution, however I am getting an error (image is attached), which says "Failed to evaluate variable ... Domain 1, 10". Material of Domain 1 and 10 is Air.
Does anyone can explain what am I doing wrong?
Thanks in advance.
