Can Neural Networks Learn Nanoscale Friction?
Mahboubeh Shabani, Andrea Silva, Franco Pellegrini +6
Current nanofriction experiments on crystals, both tip-on-surface and surface-on-surface, provide force traces as their sole output, typically exhibiting atomic size stick-slip osc…
Resistive switching suppression in metal/Nb:SrTiO Schottky contacts prepared by room-temperature Pulsed Laser Deposition
Renato Buzio, Andrea Gerbi
Deepening the understanding of interface-type Resistive Switching (RS) in metal/oxide heterojunctions is a key step for the development of high-performance memristors and Schottky…
Solid lubrication by wet-transferred solution-processed graphene flakes: dissipation mechanisms and superlubricity in mesoscale contacts
Renato Buzio, Andrea Gerbi, Cristina Bernini +3
Solution-processed few-layers graphene flakes, dispensed to rotating and sliding contacts via liquid dispersions, are gaining increasing attention as friction modifiers to achieve…
Phase-Space Ab-Initio Direct and Reverse Ballistic-Electron Emission Spectroscopy: Schottky Barriers Determination for Au/Ge(100)
Andrea Gerbi, Renato Buzio, Cesar Gonzalez +2
We develop a phase-space ab-initio formalism to compute Ballistic Electron Emission Spectroscopy current-voltage I(V)'s in a metal-semiconductor interface. We consider injection of…
Sliding friction and superlubricity of colloidal AFM probes coated by tribo-induced graphitic transfer layers
Renato Buzio, Andrea Gerbi, Cristina Bernini +2
Colloidal probe Atomic Force Microscopy (AFM) allows to explore sliding friction phenomena in graphite contacts of nominal lateral size up to hundreds of nanometers. It is known th…
Graphite superlubricity enabled by triboinduced nanocontacts
Renato Buzio, Andrea Gerbi, Cristina Bernini +2
Colloidal probe Atomic Force Microscopy allows to explore sliding states of vanishing friction, i.e. superlubricity, in mesoscopic graphite contacts. Superlubricity is known to app…
Magnetic-Field Tunable Intertwined Checkerboard Charge Order and Nematicity in the Surface Layer of SrRuO
Carolina A. Marques, Luke C. Rhodes, Rosalba Fittipaldi +7
In strongly correlated electron materials, the electronic, spin, and charge degrees of freedom are closely intertwined. This often leads to the stabilization of emergent orders tha…
Ultralow friction of ink-jet printed graphene flakes
R. Buzio, A. Gerbi, S. Uttiya +7
We report the frictional response of few-layer graphene (FLG) flakes obtained by liquid phase exfoliation (LPE) of pristine graphite. To this end, we inkjet print FLG on bare and h…
CDW slips and giant frictional dissipation peaks at the NbSe surface
Markus Langer, Marcin Kisiel, Rémy Pawlak +8
Accessing, controlling and understanding nanoscale friction and dissipation is a crucial issue in nanotechnology, where moving elements are central. Recently, ultra-sensitive nonco…
Noncontact dissipation reveals critical central peak in SrTiO3
M. Kisiel, F. Pellegrini, G. E. Santoro +8
The critical fluctuations at second order structural transitions in a bulk crystal may affect the dissipation of mechanical probes even if completely external to the crystal surfac…
Tc=21K in epitaxial FeSe0.5Te0.5 thin films with biaxial compressive strain
E. Bellingeri, I. Pallecchi, R. Buzio +7
High purity epitaxial FeSe0.5Te0.5 thin films with different thickness were grown by Pulsed Laser Ablation on different substrates. By varying the film thickness, Tc up to 21K were…
High quality epitaxial FeSe0.5Te0.5 thin films grown on SrTiO3 substrates by pulsed laser deposition
E. Bellingeri, R. Buzio, A. Gerbi +6
Superconducting epitaxial FeSe0.5Te0.5 thin films were prepared on SrTiO3 (001) substrates by pulsed laser deposition. The high purity of the phase, the quality of the growth and t…
