Increased Light Extraction of Thin-Film Flip-Chip UVB LEDs by Surface Texturing

/forschung/publikationen/increased-light-extraction-of-thin-film-flip-chip-uvb-leds-by-surface-texturing

Ultraviolet light-emitting diodes (LEDs) suffer from a low wall-plug efficiency, which is to a large extent limited by the poor light extraction efficiency (LEE). A thin-film flip-chip (TFFC) design…

Suppression of particle formation by gas- phase pre-reactions in (100) MOVPE-grown β- Ga2O3 films for vertical device application
