Abstract

InGaN-based nanocolumn LEDs from ultraviolet to red were fabricated through self-assembly of GaN nanocolumns by rf-MBE. Ti-mask selective area growth (SAG) was employed to fabricate uniform arrays of InGaN/GaN nanocolumns, and the photoluminescence observation of the arrays demonstrated that the emission color changed from blue to red with increased nanocolumn diameter.
