RESEARCH INTERESTS

Dr. Wang has quite broad research areas. He has conducted several research projects: high Tc superconducting materials, ferroelectric/piezoelectric materials and devices, magnetic materials and devices, and optics. Dr. Wang's research efforts and results in these fields have been published in journals.

Currently Dr. Wang's research projects are: ferroelectric, piezoelectric materials and devices and high Tc superconducting materials. Dr. Wang recently received a grant for research project "Studies of Piezoelectric Materials and Devices" (SPMD). The "Electronic Materials and Devices Research Laboratory (EMDRL) designed for the project in Department of Physics at Southern University and A&M College will be established under the supervision of Dr. J.T. Wang, the project principal investigator. In the research laboratory, the ferroelectric/ piezoelectric materials, and single crystals will be prepared. Using high volt poling technique, the polar materials are produced. The materials produced will be then characterized with the X-Ray diffraction measurement, microscopic observation, I-V curves, dielectric and piezoelectric measurements. By these measurements the electronic properties of these materials vs the temperature, stress/strain and frequency are studied. These studies are expected to result in possible device fabrications and applications such as transducers (actuators and sensors). These devices have a great demand by electronic and military industries.

Dr. Wang is also interested in high Tc superconductivity research including materials synthesis, impurity effect, texturing and single crystal growth. The studies are involved in resistivity and magnetization measurement with Quantum Design SQUID. These studies are expected to gain insight into the mechanism responsible for the high Tc supercoonductivity and the weak-link effect on the critical current density and critical magnetic field.

Dr. Wang plans to expand his research to the following areas: superconducting/ ferroelectric, piezoelectric thin film by laser ablation or ion sputtering technique, giant magnetoresistance studies and optics in the near future.
