Developing new magnetic materials and spin-based functionalities

The focus of our research is to develop materials and devices that take advantage of electron's spin. Electrons posses charge and spin. Modern semiconductor technologies utilize electron's "charge" to process and store information. On the other hand, magnetism arise from the collective interaction of electron's spin. Spintronics combines the two handles and provides new paradigms for functional information processing and storing devices.
 Our group works on all aspects of Spintronics research: physical science, materials engineering, device processing and characterization. We study a wide range of materials including metals, semiconductors and insulators, inorganic and organic materials including graphene, and heterostructures to develop novel spintronics devices.
