Laser actuation of cantilevers for picometre amplitude dynamic force microscopy

Evans, Drew; Tayati, Ponlawat; An, Hongjie; Lam, Ping Koy; Craig, Vincent; Senden, Timothy


As nanoscale and molecular devices become reality, the ability to probe materials on these scales is increasing in importance. To address this, we have developed a dynamic force microscopy technique where the flexure of the microcantilever is excited using an intensity modulated laser beam to achieve modulation on the picoscale. The flexure arises from thermally induced bending through differential expansion and the conservation of momentum when the photons are reflected and absorbed by the...[Show more]
