Temperature Decrease Caused by Voltage Generation in MIM Structure of Polyimide Langmuir-Blodgett Film

Abstract

Voltage was generated in metal-insulator-metal (MIM) structure of Al/polyimide Langmuir-Blodgett (LB) insulating film/Au which was fabricated in 1986. It was shown in the present paper that temperature decrease caused by the voltage generation was ascertained by noncontact temperature measurement using a Vacuun Avalanche Photodiode. Temperature decrease of the MIM was O.026°C at 0.3 Vin voltage generation. This value of temperature decrease about coincides with theoretical value which was calculated assuming specific heat and specific gravity of polyimide LB film as 1 Jg^-1K^-1 and 1g/cm³. Therefore, the present MIM seems to be a energy converter which convert thermal energy to electrical energy.
