Organic molecular beam deposition (OMBD) research. Italian scientist Roberto Zamboni using apparatus to deposit thin films of organic materials. He is adding liquid nitrogen, used to maintain a vacuum. The thin films have a range of applications, from light-emitting properties that could be used in display screens, to semiconductor properties that could be used in electronics. Also known as molecular beam epitaxy (MBE), the materials being used are heated and slowly evaporated in a vacuum, and deposited molecule by molecule on to a substrate, building up a thin film with the right properties and composition. Organic materials can provide a wider range of properties than inorganic materials.
