In the past decade, there has been a burst of new and fascinating physics associated to the
unique properties of two-dimensional exciton polaritons, their recent demonstration of …

We have studied the effects of an external electric field on photoluminescence spectra and
carrier lifetimes in strained In x Ga 1− x N/G a N quantum wells embedded in p− i− n light …

We study an asymmetric double InGaAs quantum well using optical two-dimensional
coherent spectroscopy. The collection of zero-quantum, one-quantum, and two-quantum two …

Semiconductor quantum well structures have been critical to the development of modern
photonics and solid-state optoelectronics. Quantum level tunable structures have introduced …

We present direct experimental evidence of Anderson localization induced by the intrinsic
alloy compositional disorder of InGaN/GaN quantum wells. Our approach relies on the …

We have measured both spectrum-and time-resolved photoluminescence (PL) of
InGaN/GaN light-emitting diode structure as a function of an external bias. From spectrum …
