Abstract:
1. A semiconductor light-emitting element including a support substrate and a semiconductor film provided on the support substrate, wherein the semiconductor film includes: a current-spreading layer provided on the support substrate and made from GaInP or GaP having a p-type conductivity; a first p-clad layer provided on the current-spreading layer and made from AlInP having a p-type conductivity; and a second p-clad layer provided on the first p-clad layer and made from AlGaInP having a p-type conductivity; an active layer including at last one layer made from GaInP or AlGaInP, the active layer being provided on the second p-clad layer; a first n-clad layer provided on the active layer and made from AlInP having a carrier density of 1×10 a second n-clad layer provided on the first n-clad layer and made from AlGaInP having a carrier density of 1×10 the proportion of the layer thickness of the first p-clad layer, in relation to the layer thickness of an entire p-clad layer comprising the first p-clad layer and the second p-clad layer, is 50% to 80%; the layer thickness of an entire n-clad layer comprising the first n-clad layer and the second n-clad layer is equal to or greater than 2 μm; the proportion of the layer thickness of the first n-clad layer in relation to the layer thickness of the entire n-clad layer is equal to or greater than 80%; and the layer thickness of the second n-clad layer is equal to or greater than 100 nm.
