Abstract:
1. A method of producing a semiconductor light-emitting element, comprising: forming a first layer of GaAs layer on a semiconductor substrate having Ga by providing As forming a second layer of InAs thin film layer having a plurality of InAs quantum dots on the first layer of GaAs layer by providing In and As forming a third layer of InGaAs layer on the second layer of InAs thin film layer having the plurality of InAs quantum dots by providing In, Ga and As forming a fourth layer of GaAs layer on the third layer of InGaAs layer by providing Ga and As an InGaAs layer having a high In content is formed at an interface between the InAs quantum dots and the third layer of InGaAs layer, and the amount of In contained in the InGaAs layer is gradually decreased in a direction away from the interface.
