Özet:

 

The bismuth telluride  Bi2  Te3    nanostructure powders and pellet was successfully developed for thermoelectric applications by using a simple chemical process. Several characterization tools such as X-ray diffraction  XRD , scanning electron microscopy  SEM ,  energy dispersive X-ray  EDX , atomic force microscopy  AFM  and Fourier transform  infrared  FT-IR  spectrometry were carried out. The XRD, SEM, EDX, and FTIR analyses showed that the chemical structure of pellet is Bi2  Te3  . The average crystalline size of  the Bi2  Te3   pellet is found to be 3.93 nm, as determined by the SEM. The AFM studies  confirmed that the pellet is of nanostructure form and average surface roughness value  is 68.06 nm. This is within the roughness range which can lead to an enhancement in  thermoelectric properties of Bi2  Te3   nanostructure. This could be evidenced by thermal  conductivity which should be higher than the electrical conductivity.
