Abstract

Using a properly rescaled Planck's law, the emission spectrum from nanostructures having one or two dimensions in the nanometric length scale is studied. We account for size and shape effects on the radiative heat exchange between nanostructures. This rescaling involves a sizedependent hypothetical temperature obtained from Wien's displacement law. We derive analytical expressions for the absorption cross section and heat conductance in terms of both the length characterizing the shape-anisotropy and the control temperature. Comparison with the experimental data shows a remarkable agreement
