COMSOL 6.4 - The Semiconductor Module Study Capabilities by Physics Interface

The Semiconductor Module Study Capabilities by Physics Interface

Table 1-1 lists the physics interfaces specific to semiconductor modeling and this module. It includes the physical quantities solved for and the standard abbreviation each one uses. The physical quantities in these interfaces are:

•

The electric scalar potential, V

•

The electron concentration, N

•

The hole concentration, P

•

The wave function, psi
