Spin-based electronics or spintronics exploits spins of electrons to process, store, and transmit information, rendering a new spectrum of functionalities inaccessible for conventional electronics. Specifically, in my group we develop novel methods to synthesis nanowires and heterostructures based on half-metallic oxides and chalcogenides and to fabricate devices to harness their high spin polarization.
|Functional composite nanomaterials|
|We exploit the synergy between different emergent materials and develop new synthesis strategies. For example multiferroic composites are used as a novel approach to couple ferroelectricity and ferromagnetism and to effectively manipulate magnetization and electric polarization.|
|Field effect devices and sensors|
We construct thin film and nanowire field effect devices incorporating high-k dielectrics to investigate the doping effect and to navigate the phase diagrams of emergent materials. We also construct rational nanomaterials-based devices as chemical and biological sensors.
