dependence of the electron’s eective mass on its energy above the band edge need to
be taken into account. Reviews and description of recent developments can be found in
Popov (2004), Gruzdev (2007), Jupé et al. (2009), and Gulley (2010).
5.2.3.3 Electron Heating and Impact Ionization
During the interaction with the fs pulse, CB electrons can scatter o other electrons,
holes, and phonons, as well as relax into trap and defect states. In addition, the pho-
non distribution also changes. Numerical simulations based on the Boltzmann equation
produce the temporal evolution of t ...
