X-ray flux variation. (a) XBIC profiles at different X-ray fluxes, Φ, for the InP nanowire (Φ0 = 2.6 × 106 s−1). The drawing nanowire indicates the nominal segment lengths. (b) Magnitude of the XBIC peak versus Φ. The solid line is calculated according to equation (1), and the dashed line is a linear fit to the measured data. (c) Fitted decay lengths, Ll and Lr, for InP 2 and InGaP versus Φ. The error bars are a result of the decay length fitting (see Fig. S1). |
