In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

We report on a comparative study of efficiency droop in polar and non-polar InGaN quantum well structures at T = 10K. To ensure that the experiments were carried out with identical carrier densities for any particular excitation power density, we used laser pulses of duration ~100fs at a repetition rate of 400 kHz. For both types of structure efficiency droop was observed to occur for carrier densities of above 7×1011 cm-2pulse-1 per quantum well; also both structures exhibited similar spectral broadening in the droop regime. These results show that efficiency droop is intrinsic in InGaN quantum wells, whether polar or non-polar, and is a function, specifically, of carrier density.
