the local electrical properties of 
individual defects and internal interface segments

with respect to their microstructure

General research statement of DIIL

The Defects and Internal Interfaces Lab (DIIL) studies local electron transport properties across microstructural defects in alloys and across interfaces between metallic materials.

Electron scattering is usually enhanced at defects and internal interfaces of materials, leading to energy loss and a decline in the performance of materials and devices. Detecting and understanding the associated resistivity mechanisms is the key to improve electrical properties of alloys, while keeping their high-mechanical performance. Eventually, the contribution of individual microstructural features to the electrical resistivity is poorly understood. On that account, the mission of DIIL is:

  • Develop methodologies to perform quantitative scanning electron microscopy (SEM) in-situ local electrical measurements on complex microstructures.

  • Discover the associated electron scattering mechanisms by combining advanced electrical and microstructural characterization.

  • Establish defect-design concepts of materials and internal interfaces for high-conductivity high-strength applications.
