In this research, we investigated the degree of linear polarization of GaAsSb-capped InAs quantum dots by photoluminescence measurement. As a result, the DLP of 15%-Sb sample is 3.4% and the DLP of 25%-Sb sample is 11.7% at 13 K. This result shows that the DLP beacomes larger for the higher Sb content. I think it is important for understanding the optical property of GaAsSb-capped InAs quantum dots and its future application.
