4. Physical Models

MODELS which account for the specific physics in a given semiconductor device are crucial for device modeling. This chapter starts with a discussion of the carrier transport models used, and their boundary conditions, and finally introduces lattice, thermal, and transport properties of the relevant materials. The latter also includes a discussion on polarization effects characteristic to III-N semiconductors and essential to HEMT structures.
