[en] Imaging of buried epitaxial InAs QDs as well as thin films of PbS QDs was carried out by means of local photocurrent measurements using a conductive atomic force microscope. InAs dots appear as dark areas in the photocurrent map and PbS:PCBM thin films form domain-like structures showing enhanced photoactivity.
