TL;DR: The nanorod sidewall provides an effective pathway for exciton dissociation that significantly improves the optical performance of InGaN/GaN MQWs and provides new insights into excitonic and charge carrier dynamics of quantum confined materials as well as the influence of surface states.

TL;DR: In this article, an energy selective carrier transfer can be achieved at the device level by integrating the emitter and receiver into a nano-optical resonator, where both the photon emission and absorption are significantly amplified by a near-field coupling around the resonant frequency.
