Abstract: Thermoelectricity in general is of strong scientific and technologicalinterest due to its application possibilities ranging from clean energy to photonsensing devices. Recent developments in theoretical studies on t hethermoelectric effects, as well as the newly discovered thermoelectric materialsprovide new opportunities for wide applications. One type of these materials isbased on the strongly correlated electron systems; typical examples are thetransition metal oxides, which were not regarded as very promising forthermoelectric applications. In this paper, we discuss some recent progress inthis field, and special emphasize is on the new application of thin films grownon vicinal cut substrates. The thermoelectric effect is based on the anisotropicSeebeck components in crystals. Upon radiation of heat and/or light on the filmsurface, there will be an induced voltage, hence device which can detect theheat and/or light radiation can be made. We’ll show that this type of detectordemonstrates novel properties: broad optical response, very fast time responseand at the same time it does not need any bias, therefore it is extremely energysaving. The performance of three typical compounds YBa2Cu3O7, LaCaMnO3and LaSrCoO3 are presented.
