Non-traditional Semiconductors

New electronic materials will allow us to us to exceed the limitations of traditional silicon electronics, and to exploit new possibilities such as printability and flexibility.

Time resolved transport measurements

We developed a time-resolved surface potential (KPFM) technique to probe how charges are injected and extracted from thin films.

Earlier Work: Magnetic Nanostructures

Domain walls in ferromagnetic nanowires and nanorings have been proposed for data storage. We developed a technique to apply a local circular field to manipulate and study these domain walls.

Earlier Work: Biofilms

Bacterial biofilm formation plays a critical role in public health. The specifics of their early stage formation were studied using specialized AFM techniques.
