| 中文摘要 | the transmiss on time and tunneling probability of an electron through a double quantum dot are studied using the transfer matrix technique. the time-dependent schrodinger equation is applied for a gaussian wave packet passing through the double quantum clot. the numerical calculations are carried out for a double quantum clot consisting of gaas/inas material. we find that the electron tunneling resonance peaks split when the electron transmits through the double quantum dot. the splitting energy increases as the distance between the two quantum dots decreases. the transmission time can be elicited from the temporal evolution of the gaussian wave packet in the double quantum dot. the transmission time increases quickly as the thickness of tire barrier increases. the lifetime of the resonance state is calculated tram the temporal evolution of the gaussian-state at the centers of quantum dots. |
