Technology Overview
Current perovskite thin film growth techniques are not compatible with perovskite oxide materials as the aggressive oxidizing conditions used in synthesis damages the 2D material that they are grown on. Researchers at the University of Minnesota have developed a novel method for the growth of freestanding perovskite oxide membranes via hybrid molecular beam epitaxy. This approach uses volatile metal-organic precursors without an additional source of oxygen to allow the growth of perovskite oxide films on 2D materials. This method enables the film to be transferred off of the 2D material for application elsewhere.
