Description/Abstract

The spectra of nuclear resonances provide a powerful microscopic probe of condensed matter, yet nuclear magnetic resonance (NMR) techniques have nflt so far been used to study semiconductor heterostructures. That is because only a tiny fraction of all the nuclei lie In the region of Interest, and conventional NMR cannot distinguish these. We report the first observation of optically detected NMR (ODNMR) of spatially selected nuclei In a semiconductor quantum well using an optical pumping technique which has the sensitivity and selectivity to overcome the limitations of conventional NMR. The sample is a 200 Angstrom thick single quantum well made p-type by applied electrical bias with a degenerate hole population of 10As resonance, shown In Fig. 1, which we attribute to the residual strain present in the GaAs layer
