Low-Cost Substrates for High-Performance Nanorod Array LEDs

PDF Version Also Available for Download.

Description

The completed project, entitled “Low-Cost Substrates for High-Performance Nanorod LEDs,” targeted the goal of a phosphor-free nanorod-based white LED with IQE > 50% across the spectrum from 450 nm to 600 nm on metallized silicon substrates. The principal achievements of this project included: • Demonstration of (In,Ga)N nanopyramid heterostructures by a conventional OMVPE process. • Verification of complete filtering of threading dislocations to yield dislocation-free pyramidal heterostructures. • Demonstration of electroluminescence with a peak wavelength of ~600 nm from an (In,Ga)N nanopyramid array LED. • Development of a reflective ZrN/AlN buffer layer for epitaxial growth of GaN films and GaN ... continued below
