Figure 7.

Color online. Pictorial representation of a single nanofin: end-points are maintained at fixed temperature by Nosé-Hoover thermostats. During numerical experiments for evaluating thermal conductivity, simulations are conducted in a vacuum. On the contrary, thermal boundary conductances are evaluated with the nanofin surrounded by a fluid. The latter setup can be studied by a one-dimensional continuous model, where all fields are assumed to vary only along the x-axis.
