Abstract

A method was presented to demonstrate solvothermal polyol process to prepare PbTe nanowires with tunable sized or varying diameter and length. It was observed that the 1D growth of PbTe is directed due to interaction between the Pb element in the PbTe and hydroxyl groups present in the sucrose molecules. Scanning electron microscopic analysis (SEM) revealed that the PbTe nanowires obtained from samples at 180 °C. Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) pattern revealed that each nanowire is single crystal. It was observed during the study that the size and morphology of the PbTe nanowires depend on the reaction temperature, reaction time, heating rate, and the surfactant template. An enhanced seebeck coefficient was reported because of quantum size effect or phonon drag effect.
