Mobility

The mobility is a quantity relating to the drift velocity of electrons or holes in an applied electric field across a material. The mobility depends on different processes that can decelerate the free carriers, like collisions with the lattice or scattering at crystal defects and impurities.

Hence the mobility depends on the doping concentration, defect concentration and injection. In our simulations and measurements we apply the model of DORKEL and LETURQUE[1].
