Electrical Control of Spin Relaxation in a Quantum Dot
Electrical Control of Spin Relaxation in a Quantum Dot
We demonstrate electrical control of the spin relaxation time ${T}_{1}$ between Zeeman-split spin states of a single electron in a lateral quantum dot. We find that relaxation is mediated by the spin-orbit interaction, and by manipulating the orbital states of the dot using gate voltages we vary the relaxation rate …
