Abstract
AbstractWe present a low‐temperature time‐resolved cathodoluminescence study on (In,Ga)N/GaN quantum wells grown on the (11‐22) facets of non‐coalesced ELO‐GaN. Taking advantage of the quantum confined Stark effect, such structures have been proposed as promising monolithic white light emitters. Here, we show that in order to achieve solar‐like white light emission from this kind of structure, one has to pay attention on the respective evolutions of radiative and non‐radiative QW exciton decay times along the (11‐22) facets (© 2011 WILEY‐VCH Verlag GmbH & Co.
