Special Issue Information

Control of thermal energy in and out of a device is a fundamental issue in all applications. For the device to perform at its maximum, the importance of tailoring the thermal properties of materials utilized in the device cannot be stressed enough. For example, for light-emitting diodes (LED), materials with high thermal conductivity are demanded in order to extract heat easily from the device. On the contrary, heat transfer in thermoelectric materials must be minimized to maximize the efficiency of their module. The classical heat transfer phenomena become complicated once nanostructured materials are utilized instead of bulk material.

Here, this Special Issue will address theoretical/experimental works where thermal properties of the nanostructured alloy have been tailored. Potential topics include, but not limited to:

  • Thermal properties of nanostructured thermoelectric materials (0D, 1D, 2D, 3D)
  • Thermal properties of colloidal quantum dots
  • Thermal properties of nanostructured solar cells
  • Thermal properties of nanostructured batteries and their components

Nanostructuring is considered one of the key approaches to achieve highly efficient thermoelectric alloys by reducing thermal conductivity. In this study, we investigated the effect of oxide (ZnO and SnO2) nanolayers at the grain boundaries of polycrystalline In0.2Yb0.1Co4Sb12 skutterudites on their electrical and thermal transport properties. Skutterudite powders with oxide nanolayers were prepared by atomic layer deposition method, and the number of deposition cycles was varied to control the coating thickness. The coated powders were consolidated by spark plasma sintering. With increasing number of deposition cycle, the electrical conductivity gradually decreased, while the Seebeck coefficient changed insignificantly; this indicates that the carrier mobility decreased due to the oxide nanolayers. In contrast, the lattice thermal conductivity increased with an increase in the number of deposition cycles, demonstrating the reduction in phonon scattering by grain boundaries owing to the oxide nanolayers. Thus, we could easily control the thermoelectric properties of skutterudite materials through adjusting the oxide nanolayer by atomic layer deposition method. Full article
