The photon - drag effect with electrons – acoustic phonon scattering in cylindrical quantum wire with an infinite potential is studied. With the appearance of the linearly polarized electromagnetic wave, the laser radiation field and the dc electric field, analytic expressions for the density of the direct current are calculated by the quantum kinetic equation. | VNU Journal of Science: Mathematics – Physics, Vol. 33, No. 4 (2017) 80-86 The Photon-Drag Effect in Cylindrical Quantum Wire with an Infinite Potential for the Case of Electrons – Acoustic Phonon Scattering Hoang Van Ngoc1,*, Nguyen Vu Nhan2, Dinh Quoc Vuong1 1 Faculty of Physics, VNU University of Science, 334 Nguyen Trai, Thanh Xuan, Hanoi, Vietnam 2 Hanoi Metropolitan University, Vietnam Received 05 December 2017 Revised 20 December 2017; Accepted 25 December 2017 Abstract: The photon - drag effect with electrons – acoustic phonon scattering in cylindrical quantum wire with an infinite potential is studied. With the appearance of the linearly polarized electromagnetic wave, the laser radiation field and the dc electric field, analytic expressions for the density of the direct current are calculated by the quantum kinetic equation. The dependence of the direct current density on the frequency of the laser radiation field, the frequency of the linearly polarized electromagnetic wave and the temperature of the system is obtained. The analytic expressions are numerically evaluated and plotted for a specific quantum wire, GaAs/AlGaAs. The difference of the density of the direct current in the quantum wires from quantum well and bulk semiconductor is due to potential barrier and characteristic parameters of system. These results are for every temperature and are new results. Keywords: The photon, drag effect, the density of the direct current, cylindrical quantum wire, electrons, acoustic phonon, infinite potential. 1. Introduction The photon-drag effect is explained by propagation electromagnetic wave carriers which absorb both energy and electromagnetic wave momentum, thereby electrons are generated with directed motion and a constant current is created in this direction. The presence of intense laser radiation can also influence electrical conductivity and kinetic effects in material [1]-[12]. The photon-drag effect has been researched in semiconductors [1],
