Transparent conductive oxide thin films are ubiquitously used in the electrodes enabling optoelectronic devices, ranging from photovoltaics to light emitting diodes. Organic electronic displays in particular are increasingly growing in market share. In such thin film multi-layered semiconductor and polycrystalline semiconductor devices, the internal interfaces and at the surfaces often determine the ultimate device performance and reliability. To elucidate the structure, properties and dynamics of such interfaces, the team of Dr. Ow-Yang applies atomic resolution scanning transmission electron microscopy techniques and other characterization methods in collaborations developing new transparent conductive oxide materials.
