Formation of Piezo- and Pyroelectric Matrices with the Use of Nanoprofiled Silica

Abstract

In this work, a process solution for the formation of an array of piezo- and pyroelectric structures with the use of a matrix of nanoprofiled silica is demonstrated. It is proposed to use plasma etching through a hard mask of porous anodic alumina for the formation of the matrix. Nanoparticles of a ferroelectric copolymer of vinylidene fluoride with trifluoroethylene are formed in the pores of the matrix. The results of measurements of the piezoelectric and pyroelectric responses of this structure are presented.
