Hot carrier relaxation by extreme electron-LO phonon scattering in GaN
Hot carrier relaxation has been investigated in GaN using non-resonant femtosecond excitation where electrons are excited above and below the LO phonon energy. We observe remarkably rapid electron relaxation; the electron distribution is non-thermal, with a "cut-off" occurring near E-LO. I...
