Findings from Tianjin University of Science and Technology Reveals New Findings on Advanced Material Research [Order-Induced Improvement of Thermoelectric Properties in (Bi0.2Sb0.8)(2)Te-3 Column Arrays]

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Advanced Material Research. According to news originating from Tianjin, People's Republic of China, by VerticalNews correspondents, research stated, "In this study, it was found that ordering of nanostructures creates some sort of channels that favor transport of carriers but hinder that of phonons. An oriented p-(Bi-0.2-Sb-0.8)(2)Te-3 column array film was successfully achieved.. by a simple thermal co-evaporation technique."

Our news journalists obtained a quote from the research from the Tianjin University of Science and Technology, "This column array structure entailed columns with diameter of about 40 nnn. The properties of the oriented (Bi0.2Sb0.8)(2)Te-3 column array were greatly enhanced in comparison with those of the ordinary film. The (Bi0.2Sb0.8)(2)Te-3 column array film with a thermoelectric dimensionless figure-of-merit ZT = 1.17 was obtained at room temperature. The in-plane transport mechanisms of the ordered column array and the ordinary structures, and the lattice field model, were investigated and discussed. Ordering of column array was found to be the main reason accounting for the properties improvement observed in the (Bi0.2Sb0.8)(2)Te-3 film."

According to the news editors, the research concluded: "Introduction of such uniquely ordered column array structure into thermoelectric films is therefore a very promising approach."
