FIELD: chemistry.
SUBSTANCE: semiconductor light-emitting device has an n-type region, a p-type region; a III-nitride light-emitting layer between the n- and p-type regions. The III-nitride light-emitting layer is doped to concentration of dopants between 6 × 1018 cm-3 and 5 × 1019 cm-3 and has III thickness between 50 Å and 250 Å; where the III-nitride light-emitting layer is configured to emit light having a maximum on wavelength higher than 390 nm, and content of InN in the light-emitting layer is gradient content. The invention also discloses four versions of the III-nitride light-emitting device having a light-emitting area with a double heterostructure.
EFFECT: high efficiency with high current density.
