Sliding friction and superlubricity of colloidal AFM probes coated by tribo-induced graphitic transfer layers

Autor: Renato Buzio, Andrea Gerbi, Cristina Bernini, Luca Repetto, Andrea Vanossi

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 that contact formation involves tribo-induced material transfer of graph

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 that are highly sensitive to external physical stimuli promising opportun

Publikováno v: Langmuir. 34:3207-3214

We report high-resolution surface morphology and friction force maps of polycrystalline organic thin films derived by deposition of the n-type perylene diimide semiconductor PDI8-CN2. We show that the in-plane molecular arrangement into ordered, cofa
