Charge transport in PrYCaCoO3 thin films was studied experimentally by terahertz (THz) and infrared spectroscopies and by dc conductivity measurements. The metal-insulator transition is clearly visible in THz conductivity, whereas the observed weak temperature dependence of dc conductivity is limited by inter-grain charge transport.
