Outline of Final Research Achievements

Electrocaloric effect is the phenomena of temperature change by application and removal of electric field to ferroelectric material. This study focus on the electrocaloric effect to develop small and high efficient heat pumps. In organic ferroelectric thin films, the piezoelectric contribution on the pyroelectric effect was investigated and the potential temperature change by the electrocaloric effect was revealed by using a thermodynamic phenomenological theory. Moreover, the method of direct measurement of the electrocaloric effect was also developed by using thin film thermocouples.
