Electrical control of optically pumped electron spin in a single GaAs/AlAs quantum dot fabricated by nanohole infilling

We demonstrate here electrical control of the sign of the circularly polarized emission from the negatively charged trion, going from co- to contrapolarized with respect to the circular polarization of the laser, using a GaAs/AlAs quantum dot (QD) embedded in a field effect structure. The voltage ra...
