Comsol 4.4 version have semiconductor module in it. Has anyone figure out what can be done through the semiconductor module but not through AC/DC module? It looks like semiconductor module is some calculation protocol that they combine through AC/DC and put it there.
Another way to ask this is: is it really necessary to purchase semiconductor module if we already have AC/DC module?
The Semiconductor Module permits device simulation of the fundamental physics of semiconductors through a user-friendly interface design. Charge-carrier transport methods form the basis of the module and are used to solve the drift-diffusion equations with non-isothermal or isothermal transport models. A Galerkin least-squares stabilized finite element method and the finite volume method with Scharfetter-Gummel upwinding are two numerical methods provided with the Semiconductor Module to enable semiconductor modeling.
Hello Dr Ghanshyam Singh,
Is it true that AC/DC module can build all semiconductor models, if the physics and the equations are carried out correctly? Anything that AC/DC module cannot do that semiconductor module can?
Thanks.
