On the record: Five-layer optical information storage based on two-photon excitation and nanoscale electrical data recording by scanning tunneling microscopy have been demonstrated in an optoelectrical dual-responsive thin film (see picture). The recording mechanism is ascribed to charge transfer and the conformational change is induced by light and an electric field. The data can be optically and/or electrically recorded and read.
