Size-dependent materials properties toward a universal equation.
Due to the lack of experimental values concerning some material properties at the nanoscale, it is interesting to evaluate this theoretically. Through a "top-down" approach, a universal equation is developed here which is particularly helpful when experiments are difficult to lead on a specific material property. It only requires the knowledge of the surface area to volume ratio of the nanomaterial, its size as well as the statistic (Fermi-Dirac or Bose-Einstein) followed by the particles involved in the considered material property. Comparison between different existing theoretical models and the proposed equation is done.
