Low-field mobility groups in database{ …_zb{} } and database{ …_wz{} }

There are about 23 identical groups available directly under all zincblende- and wurtzite-related groups. In this section we describe four of them, specifically all groups related to low-field mobility models:

database{ …{ mobility_constant{} } }

The constant mobility model is due to lattice scattering (phonon scattering) and leads to a constant mobility that depends only on the temperature. See Low-field mobility models for details on models.
