“…The drift diffusion (DD) and thermodynamic models were used to solve the carrier continuity and Poisson's equation. For the SiGe material parameters, we used a linear energy band gap reduction with Ge incorporation into the silicon lattice [13]. Slotboon model for band gap narrowing due to heavy doping, and ShockleyRead-Hall (SRH) and Klaassen Auger recombination models for minority carrier recombination lifetime were also considered.…”

“…Pada perancangan divais SiGe heterojunction bipolar transitor tipe npn ini persamaan mobilitas yang dipakai diambil dari persamaan yang digunakan oleh Zeljka Matutinovic-Krstelj [2]. Pada penelitian sambungan yang terbentuk berupa sambungan abrupt dan persamaan bandgap narrowing yang dipakai adalah sebagai berikut [2] ) ( 688 10 log 4 .…”

“…In our simulations we used 11.4% Ge and thus AE, = 84 meV was taken. Moreover, the ratio between the product of the effective DOS was used, as was determined from temperature dependent measurements [12], [13] by assuming Si mobility in the SiGe layer, which is correct for doping concentrations of 10'' cmP3 and higher as was shown by recent experiments for majority carriers [14]. The influence of the band-splitting on the effective DOS is a more significant factor.…”
