Abstract

Croconic acid is one of the first reported organic ferroelectrics that demonstrates high spontaneous polarization of ~ 20 μC/cm2 in normal temperature conditions [1]. The methods used for the creation of these films involves the use of a vacuum chamber and vapor deposition machine. We use an applied electric field during deposition in order to align the croconic acid dipoles and promote more uniform film growth. Samples have been prepared either on ultra flat silicon dioxide substrates or with an additional bottom gold layer, allowing for ferroelectric measurements to be made. Here we present the deposition set-up and future plans to investigate ultra-thin croconic acid films.
