Figure 2: Model results for TD density reduction in redirection reaction layer structure: (a) relative TD density for structures with initial density ρ0 = 1010cm-2 and representative values for the parameter ρ = 0.5 (1), 1 (2), 2 (3); (b) absolute TD density in case ρ = 1 and various initial densities ρ0=1010 (1), 109 (2), 108 (3) cm-2. For all plots the dislocation reaction parameter κ = 100 nm. The total layer thickness includes both redirection and reaction parts.https://www.led-professional.com/media/resources-1_articles_high-quality-gan-substrates-for-modern-led-technology_substrate2-jpg/viewhttps://www.led-professional.com/media/resources-1_articles_high-quality-gan-substrates-for-modern-led-technology_substrate2-jpg/@@images/image-1200-7e7ec70cc4165a4031eafdcf1cc05568.jpeg
