Özet

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.
