“…TAT current component, which is about four orders of magnitude lower than GR current, has negligible influence on our calculations. The TAT current can be stated as [11,14]: where m * e is the tunnelling electron effective mass, M is the matrix element associated with the trap potential assumed to be 10 À23 eV 2 cm 3 , N t is the trap density equal to 2 Â 10 11 cm À3 , Z is Planck's constant, E is the electric field strength across the depletion region. Table 1 shows some detector parameters for calculations of dark current density.…”
