METHOD OF CREATION OF COMPOSITE FERROELECTRIC NANOSTRUCTURE Russian patent published in 2014 - IPC B82B3/00 B82Y30/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to methods of synthesizing of new materials with predetermined electrophysical characteristics and can be used to create functional materials with the controlled characteristics for the needs of modern micro- and nanoelectronics. The method of creation of the composite ferroelectric nanostructure based on creation in the composite of effect of internal shifting field consists in embedding of the ferroelectric material, namely triglycine sulfate, to the porous dielectric matrix with the pore size of 10-100 nm. The embedding is carried out of a saturated aqueous solution (melt) of ferroelectric salt heated to temperatures close to the Curie temperature of the bulk ferroelectric material, and the size of the internal shifting field determining the degree of expansion of the temperature interval of existence of the ferroelectric phase is varied due to the difference in the lineal expansion coefficients of the ferroelectric material and the matrix material and also due to the total area of interaction of the of the ferroelectric material - matrix variable by selecting the size and topology of the matrix pores.

EFFECT: expansion of the temperature range of existence of the ferroelectric phase in the ferroelectric composite materials by tens of degrees.
