Experimental Investigation of Thermal Transport and Thermoelectric Performance of Si-Modified Bi₂Te₃ Thin Films
Abstract: Engineering silicon secondary phases provides an effective route to tailor charge and thermal transport in Bi2Te3-based thermoelectric thin films. In this work, Bi 2 Te 3 :Si nanocomposite thin films with Si content of 0, 2.3, 4.5 and 8.2% were prepared by RF co- sputtering and the effect of Si addition on the structural, microstructural, electrical, thermoelectric and thermal transport properties was investigated. X-ray diffraction confirmed the retention of the …
