The recombination dynamics of localized excitons in cubic In xGa1-xN/GaN multiple quantum wells grown by radio frequency molecular beam epitaxy on 3C-SiC substrate were investigated. It was observed that the Stark effect due either to spontaneous or piezoelectric polarization was inactive in cubic polytypes. The time-resolved photoluminescence (TRPL) signal showed stretched exponential decay and spectral redshift with time after excitation up to 300 K.
