Modeling and analysis of the spectral response for AlGaAs/GaAs HPTs for short wavelength optical communication

Hassan A. Khan, Ali A. Rezazadeh, and Sarmad Sohaib Detailed spectral response (SR) modeling for heterojunction bipolar phototransistors (HPTs) is presented in this work. All the related physical parameters are taken into account for the resolution of photogenerated excess minority carrier continuity equations in the active layers of the HPT. The lay ... [J. Appl.
