Lanthanum strontium manganate (La0.67Sr0.33MnO3, i.e., LSMO)/lanthanum manganate (LaMnO3, i.e., LMO) perovskite oxide metal/semiconductor superlattices were investigated for potential p-type thermoelectric applications. Growth optimizations were performed using pulsed laser deposition to achieve epitaxial superlattices of LSMO (metal)/LMO (p-type semiconductor) on strontium titanate (STO) substrates. The cross-plane Seebeck coefficient of the thermoelectric superlattice measured between the substrate and the capping layer has a value of at least 1600 μV/K measured at about 300K.
