Current-induced nanogap formation and graphitization in boron-doped diamond films
V. Seshan, C. R. Arroyo, A. Castellanos-Gomez +9
A high-current annealing technique is used to fabricate nanogaps and hybrid diamond/graphite structures in boron-doped nanocrystalline diamond films. Nanometer-sized gaps down to 1…
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…
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…
