![]() ![]() Dislocations were created at these mismatched boundaries to relax the strain.Traditionally, gaming requires upfront hardware investments in the form of a gaming console or a gaming PC. Monochromatic cathodoluminescence images indicate that Al content is different between the vertically-grown and the laterally-grown domains, suggesting that lattice mismatch strain exists between them. These boundaries were found to arise from domains grown in different directions. Another unexpected set of triangular boundaries was observed inside the AlGaN layer, which grew without any change of the growth parameters. At the AlGaN/GaN interface, a high density of dislocations was created due to lattice mismatch strain. The microstructure and optical characterizations were done using transmission electron microscopy and cathodoluminescence. Subsequent growth of AlGaN on this template involving a lateral overgrowth process exhibits interesting properties. The GaN template was grown at a low temperature in order to obtain triangle-facet growth fronts. Light emitting diodes with λ = 323 nm has been achieved on these epilayers. Dislocations were created at these mismatched boundaries to relax the strain.ĪB - Thick crack-free AlGaN films have been grown on inclined-facet GaN templates.
