Abstract

At steady state, we determine the temperature profile in a circular thin layer surrounding an inner nanodevice that acts as a source of heat. The analytical solution, under suitable boundary conditions, is obtained by means of a two-temperature model, which establishes the balance laws governing the spatial distribution of temperatures and heat fluxes. The main results are displayed when the circular thin layer is made of Bi 2 Te 3 and are discussed in view of the second law of thermodynamics.
