The temperature dependence of the thermoelectric power (TEP) of Bi2Sr,Ca 1 Y Cu&08+y samples are reported for x =0-0.9 in the temperature range 77 -300 K. TEP is positive and large for large x and decreases with decreasing x (increasing carrier concentration). TEP is negative for the x =0 sample.The results are discussed following strong correlation and the Nagaosa and Lee model.
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.
