Improving the thermoelectric performance of hydrothermally synthesized FeS2 nanoparticles by post sulfurization
(ELSEVIER, 2020-08)
In this manuscript, we have synthesized the FeS2 nanoparticles by a simple hydrothermal method. Post sulfurization of the synthesized nanoparticles for different time durations (30, 60, 90 & 120 min) was performed to obtain ...
Designing of See beck coefficient and electrical conductivity in CZTS thin films for giant power factor
(ELSEVIER, 2020-05)
In this work, we develop a new technique to simultaneously increase the Seebeck coefficient and electrical conductivity in order to achieve a giant power factor. 16 samples of CZTS thin films (TFs) are synthesized using ...
Modulation of secondary phases in hydrothermally grown zinc oxide nanostructures by varying the Cu dopant concentration for enhanced thermo power
(ELSEVIER, 2020-11)
In this study, we have successfully controlled the number of secondary phases in Zinc Oxide (ZnO) nano-structures by changing the concentration of Copper (Cu) atoms. Zinc Copper Oxide (Zn1-xCuxO) nanostructures with x = ...
