Electric field screening in atomically thin layers of MoS2: the role of interlayer coupling
Andres Castellanos-Gomez, Emmanuele Cappelluti, Rafael Roldán +3
The aim of this work is to study the electrostatic screening by single and few-layer MoS2 sheets by means of electrostatic force microscopy in combination with a non-linear Thomas-…
Highly reproducible low temperature scanning tunnelling microscopy and spectroscopy with in situ prepared tips
Andres Castellanos-Gomez, Gabino Rubio-Bollinger, Manuela Garnica +4
An in situ tip preparation procedure compatible with ultra-low temperature and high magnetic field scanning tunneling microscopes is presented. This procedure does not require addi…
Mechanical properties of freely suspended atomically thin dielectric layers of mica
Andres Castellanos-Gomez, Menno Poot, Albert Amor-Amorós +4
We have studied the elastic deformation of freely suspended atomically thin sheets of muscovite mica, a widely used electrical insulator in its bulk form. Using an atomic force mic…
Force-gradient-induced mechanical dissipation of quartz tuning fork force sensors used in atomic force microscopy
Andres Castellanos-Gomez, Nicolas Agraït, Gabino Rubio-Bollinger
We have studied the dynamics of quartz tuning fork resonators used in atomic force microscopy taking into account mechanical energy dissipation through the attachment of the tuning…
Distribution of conduction channels in nanoscale contacts: Evolution towards the diffusive limit
J. J. Riquelme, L. de la Vega, A. Levy Yeyati +3
We present an experimental determination of the conduction channel distribution in lead nanoscale contacts with total conductances ranging from 1 to 15 G0, where G0=2e2/h. It is fo…
