Abstract :
Summary form only given. .We provide evidence of the effect that a continuously varying piezoelectric field has on the emission of InGaN/GaN quantum wells (QWs). To isolate the effect of the piezoelectric field we performed CW and time dependent photoluminescence (PL) measurements in InGaN/GaN QWs with different Si doping in the barrier as a function of hydrostatic pressure.
