(a) The spin relaxation signal as a function of the interaction time at O2 for different values of the gate voltage applied on gate T, V T. Circles, triangles, and squares show the result at V T = −560, −565, −570 mV, respectively. The lines are exponential fits. (b) The spin relaxation rate as a function of δ. Circles show the experimental data and the line shows a theoretical curve considering the second-order tunneling process.
