Figure 2From: Photogenerated charges and surface potential variations investigated on single Si nanorods by electrostatic force microscopy combined with laser irradiationΔΦ − V EFM curves measured at different laser intensities for NR1 (a), NR2 (b), and NR3 (c). The experimental data are plotted with scattered dots, and the fitting results are given with lines. A fitting example of NR1 without laser is presented in the inset of (a).Back to article page
