Schematic diagram of the photoinduced AHE under (a) right-hand and (b) left-hand circularly polarized radiation. (c) The schematic diagram of the experiments. Here denotes the longitudinal electric field, m indicates the spin direction of the carriers, F is the equivalent Lorentz-like force and v is the velocity of the carriers.
Spectra of the photoinduced AHE current detected in the In0.15Ga0.85As/Al0.3Ga0.7As QWs with different longitudinal electric field ranged from 0 to 275 V/cm at a step of 25 V/cm. All of the spectra are shifted vertically for clarity.
(a) The normalized transverse current obtained by under different longitudinal electric fields ranged from 0 to 250 V/cm at a step of 50 V/cm. For clarity, some spectra are skipped and the spectra are shifted vertically. (b) The spectra of the AHE current (squares) corresponding to 1HH-1E transition (near 1.30 eV) as a function of the longitudinal electric field in the In0.15Ga0.85As/Al0.3Ga0.7As QWs. The solid line is the linear fit.
The spectra of photoinduced anomalous Hall conductivity compared to the common photocurrent of the In0.15Ga0.85As/Al0.3Ga0.7As QWs.
