Nanoscale metal-metal contact physics from molecular dynamics: the strongest contact size.
Using molecular dynamics we find that the tensile strength of the contacts between two clean platinum surfaces with nanoscale asperities is strongly size dependent with a maximum strength for contact lengths of approximately 5 nm. This is the first time a strongest size is observed in single crystals. The strengthening with decreasing size down to 5 nm results from a decrease in the initial den...
متن کاملCarbon Nanotube “T Junctions”: Nanoscale Metal-Semiconductor-Metal Contact Devices
Stable “T junctions” of single-walled carbon nanotubes forming one of the smallest prototypes of microscopic metal-semiconductor-metal contacts are proposed. The structures have been found to be local minima of the total energy on relaxation with a generalized tight-binding molecular dynamics scheme. These quasi-2D junctions could be the building blocks of nanoscale tunnel junctions in a 2D net...
متن کاملDiffusive versus Displacive Contact Plasticity of Nanoscale Asperities: Temperature- and Velocity-Dependent Strongest Size.
We predict a strongest size for the contact strength when asperity radii of curvature decrease below 10 nm. The reason for such strongest size is found to be correlated with the competition between the dislocation plasticity and surface diffusional plasticity. The essential role of temperature is calculated and illustrated in a comprehensive asperity size-strength-temperature map taking into ac...
متن کاملUniversal contact-line dynamics at the nanoscale.
The relaxation dynamics of the contact angle between a viscous liquid and a smooth substrate is studied at the nanoscale. Through atomic force microscopy measurements of polystyrene nanostripes we simultaneously monitor both the temporal evolution of the liquid-air interface and the position of the contact line. The initial configuration exhibits high curvature gradients and a non-equilibrium c...
متن کاملMicroscopic structure, dynamics, and wear at metal-metal interfaces in sliding contact.
The "generic embedded atom model" (GEAM) has been investigated recently [Phys. Rev. E 69, 021509 (2004)]] to analyze the qualitative equilibrium and nonequilibrium properties of bulk metals in both undeformed and shear deformed states. In the present work, a natural extension of the GEAM is proposed and applied to characterize the microscopic structure, dynamics, and wear at clean commensurate ...
