Prof. George’s research interests are in the areas of surface chemistry, thin film growth and nanostructure engineering. He is currently directing an internationally recognized research effort focusing on atomic layer deposition (ALD) and molecular layer deposition (MLD). This research is examining new surface chemistry, measuring thin film growth rates, characterizing the properties of films and developing new applications for ALD and MLD. Current applications are using ALD & MLD to: enhance the performance of Li ion batteries; deposit the active electrode material for Li ion batteries and supercapacitors; fabricate flexible gas diffusion ultrabarriers; and deposit ultrathin and continuous Pt films as a catalyst for PEM fuel cells. Other projects are developing new ALD and MLD processes especially in the area of hybrid organic-inorganic materials and developing new reactors for spatial roll-to-roll ALD.
