The SKPM images of Si-based Ag nanoislands and the SEM images of the corresponding tips used in the measurement. The SKPM images of Si-based Ag nanoislands acquired by using a bare Si tip (a1, a2), PtIr-coated Si tip (b1, b2), PSM-60 tip (c1, c2), and PSM-90 tip (d1, d2). The SEM images for the bare Si tip (a3), PtIr-coated Si tip (b3), PSM-60 tip (c3), and PSM-90 tip (d3)
