“…MBE is a novel method for the epitaxial preparation of thin film materials and has also been used in recent years for the preparation of skutterudite TE thin film materials [67][68][69][70][71]. MBE is a novel process for coating on substrates under ultra-high vacuum.…”

“…In addition, the smaller grain size of the films prepared at higher substrate temperatures allows for lower thermal conductivity. Makogon et al [71] investigated the phase composition and crystal structure of CoSb x (1.82 ≤ x ≤ 4.16) nanofilms grown on oxidized single-crystal silicon substrates using MBE at 200 • C. It was found that increasing the percentage of Sb in CoSb x produced different substances (Figure 10b): when the content of Sb was 64.5%, the films consisted of CoSb 2 ; when the content of Sb was 64.5% to 75%, the films consisted of CoSb 2 and CoSb 3 ; when the content of Sb was 75%, the films consisted of CoSb 3 ; when the content of Sb exceeded 75%, the films consisted of CoSb 3 and Sb. Figure 10c presents the resistivity of the skutterudite films with different Sb contents.…”

Thermoelectric material is a new energy material that can realize the direct conversion of thermal energy and electric energy. It has important and wide applications in the fields of the recycling of industrial waste heat and automobile exhaust, efficient refrigeration of the next generation of integrated circuits and full spectrum solar power generation. Skutterudites have attracted much attention because of their excellent electrical trGiovanna Latronicoansport performance in the medium temperature region. In order to obtain skutterudites with excellent properties, it is indispensable to choose an appropriate preparation method. This review summarizes some traditional and advanced preparation methods of skutterudites in recent years. The basic principles of these preparation methods are briefly introduced. Single-phase skutterudites can be successfully obtained by these preparation methods. The study of these preparation methods also provides technical support for the rapid, low-cost and large-scale preparation of high-performance thermoelectric materials.
