Thermal Performance of LSCO and LSFO Films for IR Detectors

摘要

Bolometers are widely used as thermal detectors, e.g. in thermovision, medicine, astronomy etc. Among them there are thermistor-like devices consisting of the absorbing radiant power thermally sensitive films, deposited on the substrate. To meet the requirements made for bolometers, their material should have adequate parameters and characteristics. In this paper some thermal characteristics and parameters of the conducting, perovskite type ABO_3 non-stoichionetric oxides LSCO and LSFO are discussed to evaluate their usefulness in the construction of bolometers.
