中文摘要	we investigated the transmission probability of a single electron transmission through a quantum ring device based on the single-band effective mass approximation method and transfer matrix theory. the time-dependent schrodinger equation is applied on a gaussian wave packet passing through the quantum ring system. the electron tunneling resonance peaks split when the electron transmits through a double quantum ring. the splitting energy increases as the distance between the two quantum rings decreases. we studied the tunneling time through the single electron transmission quantum ring from the temporal evolution of the gaussian wave packet. the electron probability density is sensitive to the thickness of the barrier between the two quantum rings.
