強誘電体及びこれを備えるメモリー素子、並びに強誘電体の製造方法

摘要

PROBLEM TO BE SOLVED: To provide: a ferroelectric having both of flexibility and ferroelectricity; a memory element having the ferroelectric; and a method for manufacturing the ferroelectric.;SOLUTION: A polar compound is filled in at least part of pores that a porous material including a polyimide resin and/or a polyamide imide resin has. The porous material has communicating holes which are formed by a plurality of adjacent hole parts connecting to each other. The polar compound has a dipole moment of which the value is preferably 1.00 debye or more. The porosity of the porous material is preferably 60 vol.% or more and 90 vol.% or less.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
