Efficient coupling of the inhomogeneous current spreading model to the dynamic electro-optical solver for broad-area edge-emitting semiconductor devices
/en/research/publications/efficient-coupling-of-the-inhomogeneous-current-spreading-model-to-the-dynamic-electro-optical-solver-for-broad-area-edge-emitting-semiconductor-devices
We extend a 2 (space) + 1 (time)-dimensional traveling wave model for broad-area edge-emitting semiconductor lasers by a model for inhomogeneous current spreading from the contact to the active zone…
MOVPE growth of violet GaN LEDs on β-Ga2O3 substrates
/en/research/publications/movpe-growth-of-violet-gan-leds-on-beta-ga2o3-substrates
We report that a H2-free atmosphere is essential for the initial stage of metalorganic vapour phase epitaxy (MOVPE) growth of GaN on β-Ga2O3 to prevent the surface from damage. A simple growth…
