Abstract:
1. A method for producing a Group III nitride semiconductor light-emitting device having a p cladding layer and a p contact layer on the p cladding layer, the method comprising: forming the p cladding layer at a first growth temperature; forming a capping layer on the p cladding layer, the capping layer being formed of Group III nitride semiconductor undoped or doped with Mg at a concentration of 5×10 increasing the temperature to a second growth temperature higher than the first growth temperature; and forming the p contact layer on the capping layer at the second growth temperature, wherein the capping layer is formed so as to have a thickness of 5 Å to 20 Å, the capping layer is formed of InGaN having an In composition ratio of 0 mol % to 10 mol % to a number of moles of a total Group III atoms in InGaN, the first growth temperature is 800° C. to 950° C., and the second growth temperature is 950° C. to 1100° C., a surface of the p cladding layer is not exposed during the increasing of the growth temperature from the first growth temperature to the second growth temperature.
