Abstract

Ultraviolet nonpolar InGaN/GaN light-emitting diodes were grown on trench epitaxial lateral overgrowth (TELOG) a-plane GaN template by metalorganic chemical vapor deposition. Electroluminescence measurements revealed main peak at 373 nm when injection current was 40 mA. Furthermore, cathodeluminescence observed the low-defect density wings emitted 373 nm peak and the TELOG coalescence areas emitted 443 nm due to different incorporation of indium. Meanwhile, polarization measurement shown a degree of ultraviolet peak is 28.7%.
