Welcome to the Defect Lab at ASU
At the Defect Lab we strive to bring us closer to establishing an efficient platform of energy technologies based on earth abundant and environmentally benign materials that have the potential of achieving terawatt level deployment.
Our work seeks to understand how intrinsic and extrinsic defects of the material affect electrical and optical properties and accordingly engineer the processing steps that will maximize performance. We synthesize and correlate transport properties to structural information gathered mostly by state-of-the art techniques that address the location, composition, chemical state, band structure and nearest neighbors environment of defects in a wide variety of semiconductors.
