Abstract It is shown that substrate pixelisation before epitaxial growth can significantly impact the emission color of semiconductor heterostructures. The wavelength emission from In x Ga 1−x N/GaN quantum wells can be shifted from blue to yellow simply by reducing the mesa size from 90 × 90 µm 2 to 10 × 10 µm 2 of the patterned silicon used...
