Abstract

Various examples are provided related to hydrogen plasma treatment of hafnium oxide. In one example, a method includes depositing a monolayer of a precursor on a first oxide monolayer; forming a second oxide monolayer by applying an oxygen (O) plasma to the monolayer of the precursor; and creating oxygen vacancies in the second oxide monolayer by applying a hydrogen (H) plasma to the second oxide monolayer. In another example, a device includes a hafnium oxide (HfO) based ferroelectric thin film on a first side of a substrate and an electrode layer disposed on the HfObased ferroelectric thin film opposite the substrate. The HfOfilm includes a plurality of oxide monolayers including at least one HfOmonolayer, each of the plurality of oxide monolayers having oxygen vacancies distributed throughout that oxide monolayer.
