| 摘 要： | 非对称多势垒可获得比双势垒更大的共振隧穿电流及更良好的峰谷比。通过分析单电子对任意势垒透射的理论模型,建立了任意非对称三势垒模型,研究了不同偏压和温度对透射系数的影响,并得出结论,为进一步设计非对称量子器件提供理论指导。

| Abstract: | Asymmetric multi-barrier can obtain larger resonant tunneling current and better peak-valley ratio than double barrier.By analyzing the theoretical models of single-electron transmission on any barrier,an arbitrary asymmetric three-barrier model was established.Effects of different bias and temperatures on the transmission coefficient were studied.It provides a theoretical guidance for the further design of asymmetric quantum devices. |

| Keywords: | bias temperature non-symmetric three-barrier transmission coefficient quantum wells |
