The advent of micro/nanostructures and the subsequent miniaturization of moving components for various nanotechnology applications have ascribed paramount importance to tribology and mechanics on the nanoscale. Materials with low friction and adhesion are desirable for avoiding premature failures. We present the coefficient of friction and adhesion dependence on the Young’s modulus over a range of sliding velocities for an array of materials. A contour map is developed to identify tribologically suitable materials. This approach provides a fundamental insight into the mechanical property dependence of friction and adhesion and simplifies the material selection process for nanotechnology applications.
