Investigation of low-dimensional electronic and magnetic materials, including correlated electron systems, multiferroic materials, charge-density-wave materials, transition metal oxides, and semiconductors via optical techniques, magneto-optical, electro-optical and transport measurements.
We are particularly interested in the growth and characterization of thin films of multiferroics and wide band gap semiconductors using different experimental methods, including vibrating sample magnetometer, optical spectroscopy, electro-optical and magneto-optical measurements, resistivity, and dielectric measurements. Thin films are deposited by RF Magnetron Sputtering Deposition and are charterized for structural and other physical properties. We use the PPMS (DynaCool) to study the magnetic properties, electrical, and magneto-optical properties of the thin films. Our optical studies (energy range: 0.4 - 6.5 eV) focus on investigating the structural characteristics, the electronic structures, the spin-lattice-charge coupling processes, and the phase transitions in the materials.
