Basis for improved UV LEDs – high-quality aluminum nitride by high-temperature annealing
/en/research/research-news/basis-for-improved-uv-leds-high-quality-aluminum-nitride-by-high-temperature-annealing
The combination of high-temperature annealing with epitaxial growth on a sapphire surface results in aluminum nitride base layers with very low defect density. This increases the light emission and…
Ultra-narrow linewidth diode lasers for spaceborne quantum photonics
