Effect of gate-driven spin resonance on the conductance through a one-dimensional quantum wire

Abstract: We consider quasiballistic electron transmission in a one-dimensional quantum wire subject to both time-independent and periodic potentials of a finger gate that results in a coordinate-and time-dependent Rashba-type spin-orbit coupling. A spin dependent conductance is calculated as a function of external constant magnetic field, the electric field frequency, and potential strength. The results demonstrate the effect of the gate-driven electric dipole spin resonance in a transport phenomenon such as spin-flip … Show more

“…This type of interaction leads to band splittings and enriched spintronic effects [18,19]. In semiconductor quantum wires with parabolic confinement, the presence of localized Rashba interaction has been predicted to yield Fano antiresonances [20][21][22][23][24][25], to help the detection of entangled electrons [26][27][28], and to assist electron-spin resonance manipulation [29][30][31]. The effect of nonhomogeneous Rashba couplings has also been considered in the transport characteristics of two-dimensional systems [32][33][34][35][36].…”

“…Similarly, local and time-dependent Rashba SOI (induced by finger gates) can be accessed via transport in wires 26 . This represents, however, only an indirect and not reliable measurement, especially because the SOI gets induced or modified by the QD geometry itself via the local electric fields of the confining gates.…”

“…The electron spin modification in semiconductor nanowires has been studied in Refs. 17,20,21 Bringer and Schäpers 17 demonstrated the spin precession and modulation in a cylindrical nanowire resulting from the Rashba SOI. The shape-dependent spin transport has been studied in semiconductor nanowires without and with the SOI taken into account.…”

“…In the last years, the application of the SOI to the manipulation of electron spins in semiconductor nanodevices has been a subject of numerous papers. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] In Ref. 16, the conductance oscillations due to the Rashba SOI have been investigated in twodimensional stripes.…”
