Development of Bismuth Telluride Nanostructure Pellet for Thermoelectric Applications

Abstract

The bismuth telluride (Bi2Te3) nanostructure pellet was successfully developed for thermoelectric applications by using a simple chemical process. The different type of measurements such as X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), atomic force microscopy (AFM) and Fourier transform infrared spectrometry (FT−IR) were employed to the synthesize Bi2Te3 nanostructure powders and pellets. The XRD, SEM and EDX showed that the pellet were contain the Bi2Te3. The average crystalline size of the pellet was 3.93 nm. The AFM studies also confirmed that the pellet was nanostructure form and average surface roughness value was 68.06 nm. The FTIR spectrum of the developed pellet had a similar behavior of Bi2Te3 nanostructure form.
