How to calculate impact ionization phenomena and avalanche breakdown in III-V semiconductors superlattice.
Here we focus on the electrons with a certain kinetic energy , collisions with lattice. It makes an electron in the valence band being stimulated to the conduction band , and those electrons will participate in conduction.
I want to calculate electron-impact ionization rates in seiconductor and re-calcaulate them for new structures.
* Referrence to "theroy of the ionization of atom by electron impact" review of modern physic ,1968, Vol.40 No.3,pp565-587
