It is shown that substrate pixelisation before epitaxial growth can significantly impact the emission color of semiconductor heterostructures. The wavelength emission from In<sub>x</sub>Ga<sub>1-x</sub>N/GaN quantum wells can be shifted from blue to yellow simply by reducing the mesa size from 90 × 90 µm<sup>2</sup> to 10 × 10 µm<sup>2</sup> of the patterned silicon used as the substrate. This color shift is mainly attributed to an increase of the quantum well thickness when the mesa size decrea ...[more]
