Semiconductor-based LEDs suppress non-radiative energy dissipation, increasing internal quantum efficiency in solid-state lighting

"internal reflection traps up to 96% of generated photons within material, severely limiting raw light extraction... overcome using thin, branched semiconductor nanowires mitigating internal light trapping... central core acts as charge carrier injector/ delegates light emission to sub-wavelength nanoscale branches, preventing photon reabsorption/ theoretical trapping mechanisms... future: optimize to overcome surface defect losses... lower: manufacturing costs, display/ lighting electricity consumption"
