Abstract
Abstract A new pyroelectric differential thermal analyzer is devised based on a thin, narrow NiCr film heater and two symmetric electrodes (the sample-electrode and the reference-electrode) simultaneously deposited on thin z-cut LiTaO3 wafer. A NiCr ground plane is used on the other face. A specific study on liquid film vaporization of the Isopropyl alcohol has been examined at low excess temperature. A responsivity of 3.6 volts/calorie was measured with signal accuracy 1 μV.
