Dynamics of quartz tuning fork force sensors used in scanning probe microscopy
Andres Castellanos-Gomez, Nicolas Agraït, Gabino Rubio-Bollinger
We have performed an experimental characterization of the dynamics of oscillating quartz tuning forks which are being increasingly used in scanning probe microscopy as force sensor…
Optical identification of atomically thin dichalcogenide crystals
Andres Castellanos-Gomez, Nicolas Agraït, Gabino Rubio-Bollinger
We present a systematic study of the optical contrast of diselenide (NbSe2) and molybdenum disulphide (MoS2) flakes deposited onto Si wafers with a thermally grown SiO2 layer. We m…
Characterization of single-molecule pentanedithiol junctions by inelastic electron tunneling spectroscopy and first-principles calculations
Carlos R. Arroyo, Thomas Frederiksen, Gabino Rubio-Bollinger +4
We study pentanedithiol molecular junctions formed by means of the break-junction technique with a scanning tunneling microscope at low temperatures. Using inelastic electron tunne…
