圆柱形复合量子线中电子的能量和寿命

在有效质量近似下，用数值计算方法得到在圆柱形复合量子线中电子的准定态能量和寿命．对HgS／CdS／HgS量子线系统具体计算表明：在分立准定态区域中，电子的能量随波矢按平方规律增大而增大，随势阱宽度增大而减小；而寿命随波矢和阱宽的变化则相反．

Energies and Lives of the Electrons in the Quantum Wire

The quasi stationary energies and lives of the electrons in the circular cylindrical compound quantum wire are given with the numerical calculation method and the the effective mall equiplent approximation. The calculated results in the HgS/CdS/HgS quantum wire system show: in the discrete quasi stationary areas, the energies of the electrons increase if the wave vectors increase with the square law and decrease if the potential well width increases; the lives of them decrease if the wave vectors increase with the square law and increase if the potential well width increases.
