Brief review on cathodoluminescence application in solid-state devices

Abstract

Abstract In this review, the chronological advances of solid state lighting (SSL) alongside the theoretical predictions was examined. The discussion includes its crystallographic orientations, substrate growth, colour rendering, misfit dislocations, quantum well fabrication, stacking fault and energy efficiency. It has been discovered that the challenges confronting the potential of SSL devices may not just be ambient temperature of the operating environment or the safe limits of the blue/white-light hazard. This paper sheds lighter on the physics responsible for the SSL white lighting, wave function lapping at different crystallographic orientations and stress relaxation limits of quantum well (QW) heterointerfaces.
