Fig. 4: Valley-enhanced EDSR.

a Rabi oscillations at different magnetic fields (364, 365, 368 and 385 mT) for a constant drive amplitude (VAC = 1 mV). b Experimental Rabi frequency and relaxation rate from spin-valley model as a function of the externally applied magnetic field. The Rabi frequency follows the same trend as the spin-valley contribution of the relaxation rate by increasing in the vicinity of the spin-valley degeneracy. Inset: colormap of Rabi oscillations as a function of field.
