Fig. 1 (IMAGE) Osaka University Caption (a) Schematic image of photoinduced force microscopy. (b)(c) Photo-induced force microscopy images of a quantum dot measured using different wavelengths (600 nm, 520 nm). (d) Photoinduced force profiles for the images. This reflects the electronic energy structure designed for photocatalysis.
