Abstract
III-nitride semiconductor system is widely used in many electronic and optoelectronic applications. The presence of extremely high piezoelectric field in quantum wells (QWs) is known to cause severe separation of electron and hole wavefunctions and limits the thickness of QWs used in devices. We have recently shown that wide QWs are also a viable solution in optoelectronic devices. In this paper we will discuss the physics of recombination in wide InGaN QWs. We will show that the piezoelectric field is fully screened in case of wide InGaN QW and light emission occurs through excited states with high wavefunction overlap.
