- The completed project, entitled âLow-Cost Substrates for High-Performance Nanorod LEDs,â 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: â¢ Demonstration of (In,Ga)N nanopyramid heterostructures by a conventional OMVPE process. â¢ Verification of complete filtering of threading dislocations to yield dislocation-free pyramidal heterostructures. â¢ Demonstration of electroluminescence with a peak wavelength of ~600 nm from an (In,Ga)N nanopyramid array LED. â¢ Development of a reflective ZrN/AlN buffer layer for epitaxial growth of GaN films and GaN nanopyramid arrays on (111)Si.
