(color online) (a) Scanning electron micrograph of the GaAs double quantum dots. The blue arrow indicates the electric field and the green arrow is the direction of the static magnetic field. (b) Resonance of spin-flip by changing the amplitude of the magnetic field and the RF frequency. (c) Rabi oscillation of the EDSR experiment. The period changes along with the amplitude of the microwave. (d) Rabi frequency as a function of amplitude of the microwave (the square root of MW power). The figure comes from Ref. [105].
