Structural and Electrical Properties of Strontium Doped Lanthanum Cobaltite (LSC) thin films for SOFC Cathode

Abstract

Lanthanum Strontium Cobaltite LSC thin films with 01 02 and 03 mol strontium were synthesized by spray pyrolysis technique These thin films were sintered at 1000oC has been characterized by FESEM spectroscopy Elemental analysis also studied by EDAX DC electrical resistivity were measured with variation of temperature and it trait as semiconducting behavior Temperature dependent dielectric constant was measured at 200 KHz frequency
