This work is aimed at the investigation of the spin relaxation in controllably charged quantum dots (QDs). Measuring the dependence of the spin lifetime on the gate voltage in a heterostructure containing InP QDs, we detected the onset of spin conservation when the QD became negatively charged. The
Coherent spin precession of electrons and excitons is observed in charge tunable InP quantum dots under the transverse magnetic field by means of time-resolved Kerr rotation. In a quantum dot doped by one electron, spin precession of the doped electron in the quantum dot starts out of phase with spi
