Microscopy of porous nitride materials for long wavelength light emitting diodes
III-nitride based-RGB micro-LEDs and colour-converted (CC) micro-LEDs are two major contenders for achieving full-colour monolithic integration for micro-display applications. Each approach presents challenges, calling for innovative ways to improve the device performance from the point of view of …
