Halasyamani Research Group

Collaborations

The Halasyamani research group collaborates with scientists throughout the United States and all over the world. We have one of the few research laboratories capable of measuring second-harmonic generation, piezoelectricity, ferroelectricity, and pyroelectricity on bulk and single crystal samples (Chem. Soc. Rev. 35, 710-717, 2006). We are also able to perform refractive index measurements (5 wavelengths) and Maker Fringe measurements on single crystals. Below is a partial list of scientists who have sent samples to Prof. Halasyamani for measurement.

Individuals interested in pursuing a collaboration with Prof. Halasyamani regarding these measurements are welcome to e-mail me at psh@uh.edu.
