titleOfInvention | Gallium phosphide luminescent device |
abstract | By providing a nitrogen-doped low carrier concentration layer 13 having both of a donor concentration and an acceptor concentration controlled below 1 x 10<16>/cm<3> at a p-n junction portion between an n-type GaP layer 12 and a p-type GaP layer 14, the luminance of the GaP light emitting device can be improved by as much as 20 to 30% over the conventional one. Suppressing the donor concentration and the acceptor concentration in the low carrier concentration layer 13 below 1 x 10<16>/cm<3> inevitably gives a carrier concentration, which is expressed as a difference between both concentrations, lower than 1 x 10<16>/cm<3> accordingly. The emission efficiency upon injection of electrons or holes can be improved by suppressing the concentration of the donor which serves as non-emissive center below 1 x 10<16>/cm<3> to thereby extend the carrier lifetime; and by concomitantly suppressing the carrier concentration at a level significantly lower than that in the adjacent layers 12 and 14. <IMAGE> |
