Seebeck coefficient and electrical conductivity of the N-type and P-type Bi 2Te3-based alloys prepared by melting/grinding/hot-pressing met hod for different process parameters (temperature and pressure of hot-pressing)were measured,and the effects of process parameters were analyzed.It has been found that the temperature and pressure of hot-pressing play very important roles in enhancing both Seebeck coefficient and electrical conductivity of the Bi2Te3-based alloys.The phenomena are different from those of Bi2Te3 single cry stal and its oriented crystal in the electrical properties.Better electrical properties may be obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
