Abstract

Here we present the formation of PVDF-TrFE thin films epitaxially grown on molecularly ordered PTFE surface by spin coating and subsequent thermal annealing. Nearly single crystalline polymer films were obtained with a axis of PVDF-TrFE crystals aligned parallel to the PTFE surface normal, giving rise to the crystalline lamellae directionally oriented perpendicular to the chain axis of PTFE. Furthermore, the facile formation of uniform single crystal PTFE surface on a metallic substrate in very large area allowed us not only to fabricate arrays of ferroelectric capacitors but also FeFET with the epitaxially grown PVDF-TrFE thin film.
