Ferroelectric Nanolithography Extended to Flexible Substrates

Recent advances in materials synthesis have yielded an ever increasing array of functional components from which to assemble devices. The ultimate goal is to assemble multiple components of diverse materials types into complex configurations.

Ferroelectric Nanolithography achieves this by controlling local electronic structure on substrates that influences electron transfer at the surface.

Previously this has been accomplished on rigid oxide substrates.  Here this is demonstrated on a ferroelectric polymer.  Optical excitation of defect states in the band gap of PVDF provide electrons that interact at the surface of ferroelectric domains to produce patterned nanoparticles.  Functional molecules can be attached to nanoparticles to produce nano-sized opto electronic devices
