Special Issue Information

Dear Colleagues,

Nanostructured materials have been found to be potential thermal transport optimizers, especially in the thermoelectric (TE) fields. The preparation methods of bulk nanostructured TE materials include solid state reaction, spark plasma sintering, etc., while thin film nanostructured TE materials are prepared via pulse laser deposition, molecular beam epitaxy, etc. Nanostructured TE materials have shown interesting, surprising, and outstanding properties in energy materials fields. Every day, researchers around the globe develop new nanostructured TE material with improved functionalities for TE applications. This Special Issue aims to provide a perspective on exciting new developments in thermal/thermoelectric transport in nanostructured systems for bulk and thin films. We invite original research contributions or concise reviews both on the synthesis and characterization of thermal/thermoelectric transport in nanostructured systems, as well as their applications in TE systems. We look forward to learning more about your most recent discoveries soon.

For thermoelectric thin film, the substrate plays an important role during the growing process and produces effects on its thermoelectric properties. Some special kinds of substrates provide an optimal combination of influences on both the structure and thermoelectric properties. In this work, Bi-Sb-Te films are deposited on Si substrates with different initial orientations by magnetron sputtering in two ways: with and without a pre-coating process. The preferred orientations of the Bi-Sb-Te films are greatly affected by the substrates, in which the thin film tends to deposit on Si substrate with (100) initial orientation and high (015)-texture, while the (00l)-textured Bi-Sb-Te film easily deposits on Si substrate with (110) initial orientation. The experimental and theoretical calculation results indicate that Bi-Sb-Te film with (00l)-texture presents good electrical conductivity and a higher power factor than that of film with (015)-texture.
