Abstract

This work addresses the problem of how a nano-object adheres to a supporting media. The case of study are the serpentine-like structures of single-wall carbon nanotubes (SWNTs) grown on vicinal crystalline quartz. We develop in situ nanomanipulation and confocal Raman spectroscopy in such systems, and to explain the results, we propose a dynamical equation in which static friction is treated phenomenologically and implemented as cutoff for velocities, via Heaviside step function and an adhesion force tensor. We demonstrate that the strain profiles observed along the SWNTs are due to anisotropic adhesion, adhesion discontinuities, strain avalanches, and memory effects. The equation is general enough to make predictions for various one- and two-dimensional nanosystems adhered to a supporting media.
