Abstract

In this study, we propose a novel fabrication of an oxide-based lateral thermoelectric pn couple and investigate the characteristics of the thermoelectric couple. Electrospun ZnO and $LaSrCoO_3$ nanofibers are used as n- and p-legs of the couple, respectively. The Seebeck coefficients of the n- and p-type nanofibers and the pn couple are $-98.1{\mu}V/K$, $42.4{\mu}V/K$, and $118.8{\mu}V/K$, respectively. The thermoelectric couple generates an output voltage of $484.7{\mu}V$ at a temperature difference of 4.1 K.
