Transmission properties of an electron in the symmetric triple inverse parabolic barrier double well structure have been investigated under the intense laser field. We have found that the laser field has effects on tunneling states through the structure. By altering the structure parameter and intensity of the laser field, it can accommodate a blue or red shift in the electronic spectra according to the purpose, and these results can be used to tune and control the electronic and optic properties of these systems. We see that under the intense laser field conditions, the well width and width parameters are the effective structural parameters in determining the resonance energy. The transmission amplitude decreases at the first and second resonance energy by increasing well width. The increment of the well width causes the incident electron waves to be localized. Consequently, the transmittance decreases, and resonant peak becomes small or disappear.

强激光场对对称三重反抛物线势垒双阱结构共振隧穿特性的影响

在强激光场下,研究了对称三重反抛物线势垒双阱结构中电子的传输特性。我们发现激光场对穿过结构的隧穿状态有影响。通过改变结构参数和激光场的强度,它可以根据目的适应电子光谱中的蓝色或红色偏移,这些结果可用于调整和控制这些系统的电子和光学特性。我们看到在强激光场条件下,阱宽和宽度参数是确定共振能量的有效结构参数。传输幅度在第一和第二共振能量处通过增加阱宽度而减小。阱宽度的增加导致入射电子波被局域化。因此,透射率降低,并且共振峰变小或消失。
