摘要：
We report on the experimental evidence of the manipulation of the exciton spin in InGaN quantum dots through the application of an external electric field up to room temperature. Furthermore, we have found the exciton spin relaxation to be independent of temperature. These findings are highly promising for the potential future use of nitride semiconductor quantum dots in practical spintronic devices.
