Abstract

•High electric field guidance in situ with physical vapor deposition method was used to successfully fabricate an ultra-thin organic ferroelectric film.•The film obtained is only 20nm in thickness with±2nm in surface roughness.•The film obtained is far superior to the best-reported thin croconic acid films prepared using other methods, in terms of both thickness and surface smoothness.•The film obtained still retains the ferroelectric property of croconic acid.•The mechanism on the film formation is discussed.
