Pairing Models
I am very new to comsol software. How do I pair the two semiconductor and Schrödinger modules in Comsol? Do I have to make any changes to the Schrodinger or Poisson equations? Is there no need for multiphysics? Thanks Read more »

Modelling a Novel Photonic Silicon On Insulator PhotoActivated Modulator
This device is similar to an inverted MOSFET. The only difference is that in the device , the n-type channel is separated from the p-type substrate by a Silicondioxide layer which acts as an insulator of thickness 150 nm. But i... Read more »
