Abstract
With the help of thin-film Au-constantan thermocouples the surface temperature of mica substrates on a hotplate was measured. The improvement of the thermal contact between the substrate and the hotplate by a thin layer of aquadag was verified and the influence of the mica thickness on its surface temperature was evaluated. The thin-film thermocouple proved useful for the investigation of the effect of radiant heat from the evaporation source on the temperature of the substrate surface.
