Carbon-fiber tips for scanning probe microscopes and molecular electronics experiments
Gabino Rubio-Bollinger, Andres Castellanos-Gomez, Stefan Bilan +4
We fabricate and characterize carbon-fiber tips for their use in combined scanning tunneling and force microscopy based on piezoelectric quartz tuning fork force sensors. An electr…
Mechanical properties of freely suspended semiconducting graphene-like layers based on MoS2
Andres Castellanos-Gomez, Menno Poot, Gary A. Steele +3
We fabricate freely suspended nanosheets of MoS2 which are characterized by quantitative optical microscopy and high resolution friction force microscopy. We study the elastic defo…
Reversible hydrogenation and band gap opening of graphene and graphite surfaces probed by scanning tunneling spectroscopy
Andres Castellanos-Gomez, Magdalena Wojtaszek, Arramel +2
The effect of hydrogenation on the topography and the electronic properties of graphene and graphite surfaces are studied by scanning tunneling microscopy and spectroscopy. The sur…
Strong and tunable mode coupling in carbon nanotube resonators
Andres Castellanos-Gomez, Harold B. Meerwaldt, Warner J. Venstra +2
The non-linear interaction between two mechanical resonances of the same freely suspended carbon nanotube resonator is studied. We find that in the Coulomb blockade regime, the non…
Calibration of piezoelectric positioning actuators using a reference voltage-to-displacement transducer based on quartz tuning forks
Andres Castellanos-Gomez, Carlos R. Arroyo, Nicolás Agraït +1
We use a piezoelectric quartz tuning fork to calibrate the displacement of ceramic piezoelectric scanners which are widely employed in scanning probe microscopy. We measure the sta…
Elastic properties of freely suspended MoS2 nanosheets
Andres Castellanos-Gomez, Menno Poot, Gary A. Steele +3
We study the elastic deformation of few layers (5 to 25) thick freely suspended MoS2 nanosheets by means of a nanoscopic version of a bending test experiment, carried out with the…
