Over the past decade, nanostructured surfaces have become widely used in electronics,1 biomedicine,2 photonic crystals,3 battery technology,4 solar cells,5 etc. Independently of the area of application, the most important points of interest of nanofabrication control are the shapes that can be manufactured, including the aspect ratio of extreme shapes such as nanopillars, and the reproducibility with which the final structures can be produced. We report the fabrication of well-ordered nanopillar arrays for tribological applications. We utilize their mechanical properties in an attempt to influence the friction between dry and unlubricated surfaces. We expect friction to be affected significantly by the simultaneous and spontaneous motion of the nanopillars. We choose the dimensions of the nanopillars such that they exhibit transverse vibrations with an extremely high natural frequency of several GHz and above, in combination with a significant vibration amplitude at room temperature, typically on the order of an interatomic distance. Under these conditions, we foresee that when the nanopillars are brought into mechanical contact with a flat counter-surface, each nanopillar will conduct an independent, diffusive random walk over the counter-surface. This should reduce the lateral force required to translate the nanopillar array over the counter-surface to nearly zero at low sliding velocities. This reduction of the coefficient of friction can amount to several orders of magnitude. This behavior has been investigated theoretically for the tips of atomic force microscopes (AFM) or friction force microscopes (FFM) and is known as thermolubricity.6 In order to obtain the same behavior for the contact between two macroscopic bodies, we propose to shape one of the two surfaces in the form of a vast array of nanopillars with the same mechanical properties as the AFM or FFM tips in terms of typical vibration frequency and amplitude. For this purpose, it is essential that over distances even as large as centimeters the nanopillars all be produced with precisely the same length and with minimal variation in diameter, so that the number of nanopillars over which the contact forces are distributed is maximized and each nanopillar in the contact has the same mechanical characteristics.
