摘要

Direct and phonon-assisted mechanisms of Auger recombination in bulk n-In_xGa_(1-x)N wurtzite alloys are numerically investigated. The matrix elements of electron-electron and electron-phonon interaction are calculated using the band structure and wave functions obtained by the empirical pseudopotential method. Phonon-assisted Auger process is analyzed by the spectral density functions approach. The dependences of Auger recombination coefficient on the energy band gap of n-In_xGa_(1-x)N alloys, temperature and carrier concentration are presented. The calculated Auger coefficients for alloys corresponding to the visible spectrum exhibit strong reduction at high carrier concentration.
