Abstract
A method of depositing a material onto a substrate, comprising the steps of: feeding a material solution to an outlet to provide a stream of droplets of the material solution; applying a potential difference between the outlet and a substrate to electrostatically attract the droplets from the outlet towards the substrate such that a corona discharge is formed around the outlet; heating the substrate to provide an increase in temperature between the outlet and the substrate; and progressively increasing the temperature of the substrate during material deposition.
