Thermoelectric properties of Bi2Te3 nanoplatelets modified with Sn nanodots surface by electroless Plating

Year: 2023

Type: article

Abstract: In this study, Sn nanodots were formed on the surface of Bi2Te3 nanoplates by electroless plating. The nanodot density in nanoplates was controlled by varying the SnCl2 concentration in the plating solution. SEM and EDS analyses showed that Sn nanodots were formed on the nanoplates and that the nanodot density varied with the plating concentration. The electrical conductivity increased and the Seebeck coefficient decreased as the Sn nanodot density increased. The thermal conductivity decreased with increasing Sn nanodot density, possibly in part due to phonon scattering by the Sn nanodots.
