This thesis reports on the selective area metalorganic vapor phase epitaxy of InGaN/GaN multi-quantum wells for self-emissive micro-displays. GaN-based LEDs have been recognized to be very attractive for this application, thanks to their properties which include high brightness and efficiency allowing low power consumption and good reliability.To date, one of the main challenges ahead for the micro-displays technology is the production of full color devices integrating RGB emitting pixels, with a pixel pitch below 10 µm. This study aims to achieve wavelength modulation of InGaN/GaN multi-quantum wells using selective area growth (SAG). This technique consists in patterning the surface of a substrate with a dielectric amorphous mask. During ...
