Detailed Description

class allpix::VanOverstraetenDeMan;

van Overstraeten de Man model for impact ionization

Taken from https://www.sciencedirect.com/science/article/pii/0038110170901395; Parametrization according to Chynoweth’s law, parameter values taken from abstract.

Temperature scaling via Synopsys Sentaurus user manual, but T0 reference value for gamma_ is not entirely clear since it it never stated explicitly. Assuming 300K, Weightfield2 uses 298K.
