Abstract:
A semiconductor light-emitting device, comprising:a first substrate of a first conductivity type; a first bonding layer provided on said first substrate and consisting essentially of a GaP material of the first conductivity type; a second bonding layer provided on said first bonding layer, coincident with the first bonding layer in a crystal orientation, having the first conductivity type, and consisting essentially of a material represented by a general formula InxGayP, where 0&lE;x, y&lE;1, and x+y=1; and a light-emitting layer comprising a first cladding layer, an active layer, and a second cladding layer, which are successively provided on said second bonding layer, each of said first and second cladding layers having the first and a second conductivity types, and each of said active layer and first and second cladding layers consisting essentially of a material represented by a general formula InxGayAlzP, where x+y+z=1, and 0&lE;x, y, z&lE;1.
