Spin-polarization dynamics in electrically excited single InGaAs quantum dots

Potential applications of semiconductor quantum dots include spin memory and quantum information processing devices. For these, a rapid spin-initialization process would be desirable. In this contribution, we demonstrate nanosecond-pulsed electrical spin-injection into quantum dots embedded in a spi...
