I'm simulating the capacitance of a HEMT in off-state, and the capacitance values I got from Maxwell 2D (only simulated the cross-section), Sonnet, and Momentum are different from each other, and Maxwell 2D's result matches the experimental value very well. I wonder if 2.5D EM simulators like Sonnet and Momentum can calculate the fringing capacitance (capacitance from the edge of an electrode on top layer to the edge of an electrode on the layer below, while the to electrodes do not overlap) very accurately. Will it be helpful to shrink mesh size on the edge?
Thanks!
Thanks!
