Research Interests

One goal of modern condensed-matter science is to use constituents (mainly atoms and molecules) as the elementary bricks to build new materials. In this context, the field of clusters that concerns the aggregates of a few atoms to thousands of atoms (diameters between 1-100 nm) appears especially fascinating, since these systems are intermediate between of small molecules and bulk solids. On a fundamental level, they offer the opportunity to understand more precisely how atomic structure can lead to physical and chemical properties of macroscopic phases. Moreover, it is possible to produce in the form of clusters some atomic arrangements that do not normally exist in nature and may consequently exhibit specific properties that are not due only to the large number of surface atoms.

My research group can produce monodispersive nanoclusters with size range from 1 nm to 100 nm by our newly developed Sputtering-Gas-Aggregation (SGA) source. The unprecedented ability to assemble nanoclusters into new materials with unique or improved properties is thus creating a revolution in our ability to engineer condensed matter for desired utilization. These nanophase materials, assembled using nanoclusters as building blocks, can be synthesized to have a wide variety of controlled optical, electronic, magnetic, mechanical and chemical properties with attendant useful technological applications.

My research interests mainly include two areas:  (1) magnetic nanoclusters and cluster-assembled nanomaterials for energy and environmental applications, and (2) magnetic and optical properties of ZnO and TiO2 based nanoclusters for spintronics and solar energy applications.
