Tw. Tang et J. Nam, A SIMPLIFIED IMPACT IONIZATION MODEL-BASED ON THE AVERAGE ENERGY OF HOT-ELECTRON SUBPOPULATION, IEEE electron device letters, 19(6), 1998, pp. 201-203
A previously developed nonlocal impact ionization model based on the a
verage energy of hot-electron subpopulation has been further simplifie
d. The system of hydrodynamic transport equations consisting of three
equations for these high-energy electrons has been reduced to a single
equation. The simulation results for n(+)-n-n(+) structures are in go
od agreement with Monte Carlo (MC) calculations. The model is easily a
pplicable to two-dimensional (2-D) problems by exploiting the current
how line approach.
