چکیده مقاله:
In this present paper, the linear optical absorption coefficient in an array of quantum wires under the external electric and magnetic fields is studied. The effects of the external fields and structural parameters such as wires' radius, the number of wires, the distance between wires, and the Al composition on the optical absorption are investigated. Results indicate that the resonant peak of the absorption coefficient shifts toward the lower photon energies with increasing structural parameters. Also, results reveal that the absorption frequency is in the terahertz range and shifts to the higher (lower) energies by increasing the electric (magnetic) field. The resonant peak value of the linear optical absorption decreases by increasing the wires' radius, the distance between wires, and the Al composition, however, it changes non-monotonically with the number of wires. Also, the optical absorption reduces with the increase of the electric field and changes non-monotonically with the magnetic field.
