We report on a comparative study of the low temperature emission and polarisation properties of InGaN/GaN quantum wells grown on nonpolar ([Formula: see text]) a-plane and ([Formula: see text]) m-plane free-standing bulk GaN substrates where the In content varied from 0.14 to 0.28 in the m-plane series and 0.08 to 0.21 for the a-plane series. The low temperature photoluminescence spectra from b...

Les plans de symŽtrie sont souvent identifiŽs par lÕexistence dÕune polarisation pure perpendiculaire ˆ ces plans. Cependant, ce type de polarisation peut appara”tre sans que le plan soit un plan de symŽtrie. Les plans qui prŽsentent une polarisation pure suivant leurs normales sont appelŽs Ç plans de dŽcouplage È, car le systme de trois Žquations linŽaires couplŽes par les cosinus directeurs ...
