Figure 2

The ALPGE current as a function of the spot location near the transitions of 1hh-1e and 1lh-1e. (a) The ALPGE current as a function of the spot location corresponding to 1hh-1e and 1lh-1e. The two solid curves are the curves fitted by Equation (5). The inset denotes a schematic diagram of the experimental setup. (b) The two-dimensional colored figure denotes the ALPGE currents at different spot locations and different wavelengths (near the transitions of 1hh-1e and 1lh-1e). The uptriangles (downtriangles) mark the maximum (minimum) positions at certain wavelengths.
