Investigation of Ag2se Nanostructures for Mid Temperature Thermoelectric Applications

Abstract

CHAPTER I provides a concise and comprehensive overview of newlinethermoelectrics (TEs). It encompasses their development, history, and the barriers that newlinewere overcome through innovative insights from pioneers. It explores various newlineperspectives, concepts, materials, and mechanisms of thermoelectrics that have evolved newlineafter the discovery by Thomous Johann Seebeck on 1822. Furthur, the later part of this newlinechapter deals with the origins and advancements of TE materials based on Silver newlineSelenide (Ag2Se), including recent theoretical and experimental findings. The newlineconcluding section of the chapter outlines the significant scope, objectives, and newlinedistinctive aspects of the present thesis work. newlineCHAPTER II discusses state-of-the-art characterization techniques newlineemployed for investigating both the fundamental properties and practical applications of newlinethe prepared samples. Various analytical methods, including X-ray diffraction (XRD), newlineHigh resolution scanning electron microscopy (HRSEM), and high-resolution newlinetransmission electron microscopy (HRTEM) were utilized to explore the structure, newlinemorphology, and compositional properties of the materials. Furthermore, the newlinethermoelectric parameters such as Seebeck coefficient, electrical conductivity, and newlinethermal conductivity were measured by ZEM 3 and laser flash analyzer (LFA 467 HT) newlineinstrument newline
