Gossard. 2009. A new mechanism of electric dipole spin resonance: hyperfine coupling in quantum dots. Semiconductor Science and Technology 24(064004).0268-1242http://nrs.harvard.edu/urn-3:HUL.InstRepos:5110753A recently discovered mechanism of electric dipole spin resonance, mediated by the hyperfine interaction, is investigated experimentally and theoretically. The effect is studied using a spin-selective transition in a GaAs double quantum dot. The resonant frequency is sensitive to the instantaneous hyperfine effective field, revealing a nuclear polarization created by driving the resonance. A device incorporating a micromagnet exhibits a magnetic field difference between dots, allowing electrons in either dot to be addressed selectively. An unexplained additional signal at half the resonant frequency is presented.en-USINSBsingle-electronmagnetic-resonancefieldsemiconductorsmanipulationtransitionstransistorJournal Article2011-08-1510.1088/0268-1242/24/6/064004
