TL;DR: It is shown that both from the point of view of cost of ownership and carbon emissions reduction, the relevant metric is efficiency, more than the cost of lumens, which requires identification of the loss mechanisms in light emission from LEDs.

TL;DR: In this paper, the authors introduced a method to account for quantum disorder effects into the classical drift-diffusion model of semiconductor transport through the localization landscape theory, which solved the carrier dynamics with quantum effects self-consistently and provided a computationally much faster solver when compared with the Schrodinger equation resolution.

TL;DR: In this paper, a model of carrier distribution and transport in semiconductor alloys accounting for quantum localization effects in disordered materials is presented, which is based on the recent development of a mathematical theory of quantum localization which introduces a spatial function called localization landscape.

TL;DR: In this paper, a three-dimensional absorption model is developed based on disorder-induced localization which provides the effective potential seen by the localized carriers without having to resort to the solution of the Schrodinger equation in a disordered potential.

TL;DR: Wave destabilization is demonstrated in semiconductor ring lasers operating at low pumping levels, where ultrafast gain recovery leads to the emergence of a frequency comb regime owing to phase turbulence.
