Piezoelectric effects on PL properties are clarified in InGaN quantum wells (QWs) of 1-10 nm wide at 17 K. An extremely large change in PL peak energy (up to 200 meV) and PL decay time (two orders of magnitude) are found in a 10 nm-wide QW with increasing excitation intensity. We compare the distinctive characteristics of the field effects with QCSE in GaAs QWs and discuss possible optical device functions.
