Abstract

We present measurements on nuclear spin relaxation probed by a single quantum dot formed in a high-mobility electron gas. Current passing through the dot leads to a spin transfer from the electronic to the nuclear spin system. Applying electron spin resonance, the transfer mechanism is suppressed. Additionally, the dependence of nuclear spin relaxation on the dot gate voltage is observed. We find electron-nuclear relaxation times of the order of 10 min.
