Collaborative research is being done in materials science and biophysics. The active collaborations are with the Wayne State University (Department of Physics, and Department of Electrical and Computer Engineering), Children's Hospital of Michigan and Delphi Automotive Systems.
Wide bandgap Semiconductor
Thin films of III-nitride materials (for example aluminum nitride, gallium nitride, indium nitride, etc.), and their binary alloys (for example Al1-xInxN) prepared by plasma source molecular beam epitaxy are being investigated. The thin films are structurally characterized by x-ray diffraction, reflection high-energy electron diffraction, high- resolution transmission electron microscopy. The optical properties are studied by Raman scattering, photoluminescence and UV-visible spectroscopy.
Ferroelectric / Diluted Magnetic Semicondoctor Oxide Materials
The thin films are prepared using metalorganic decomposition methods. Ferroelectric thin films of Barium Strontium Titanate (Ba1-xSrxTiO3), and Lead Strontium Titanate (Pb1-xSrxTiO3) are studied with temperature dependent Raman scattering and dielectric measurements. Transition metal (Co, Fe, Cu...) doped TiO2 and ZnO (wide bandgap semiconductors) are being investigated for spintronic applications.
Biophysics
The current research involves Raman spectroscopic investigations of biological tissues, structure-property relationships in proteins and model peptides. Raman spectroscopic studies include various types of cancers in humans and animal models.
