Thermoelectric properties of nanocomposite Bi_2Te_3 layers prepared by PLD

摘要

Some properties of thermoelectric nano-layers prepared by Pulsed Laser Deposition prepared from Bi_2Te_3 target are presented. The layers were prepared under various deposition conditions to study its influence on the quality of the surface. Crystallinity, composition and morphology of the layers are presented. Nano crystallites observed on the layer's surface are studied by X-ray Diffraction and by Atomic Force Microscope. Results, comparison and experiences are discussed.
