Current Research Projects

Combinatorial investigation of functional materials

We have developed a comprehensive methodology for rapid mapping of previously unexplored compositional landscape in search of novel multifunctional materials. A variety of thin film deposition tools are implemented for synthesis of combinatorial thin film libraries and composition spreads of various designs. A suite of rapid characterization tools are utilized for quantitative mapping of relevant physical properties across combinatorial libraries. These include microwave microscopes, a scanning magneto-optical Kerr measurement setup and scanning x-ray diffractometers. Current topics of interest include magnetistrictive materials, multiferroic materials, and shape memory alloys. Our recent emphasis has also been on development of informatics techniques to effectively handle, visualize, and analyze the large amount of data which are generated from the combinatorial experiments. We have a network of international collaborators with whom a number of combinatorial experiments are carried out at any given time.

Novel multilayer thin film devices

Previously I had worked on fabrication and characterization of superconducting thin film devices for over 10 years. My interest in novel functional devices now spans a range of other materials including magnetic materials and various smart materials. Our current projects include various multilayer multiferroic devices.

Scanning probe microscopy

Many of the rapid characterization tools used for screening combinatorial libraries are scanning probe microscopes. For instance, we work extensively with scanning SQUID microscopes (in collaboration with Neocera, Inc.) and scanning microwave microscopes. We have recently demonstrated high sensitivity scanning magnetic probe microscopy using a magnetoelectric device. Our current project includes development of novel microwave microscopy combined with atomic resolution STM for performing spin resonance measurements.
