Background
Dr. Bassiri-Gharb began at Georgia Tech in Summer 2007 as an Assistant Professor. Prior, she was a Senior Engineer in the Materials and Device R&D group of MEMS Research and Innovation Center of QUALCOMM MEMS Technologies, Inc. Her work included characterization and optimization of the optical and electric response of the IMOD displays, and research on novel materials for improved processing and reliability of the IMOD.
Research Areas and Descriptors
Research
Dr. Bassiri-Gharb's research interests are in ferroelectric and multiferroic materials and their application to nano- and micro-electromechanical systems as sensors and actuators. Her research projects integrate micro and nanofabrication techniques and processes, with fundamental science of ferroelectric materials.
In the area of novel characterization techniques for ferroelectrics, Dr. Bassiri-Gharb studies the effects of the external fields (electric, strain and temperature) on the dielectric and piezoelectric properties of these materials. The experimental characterization and mathematical modeling of the nonlinearities in ferroelectric materials are then implemented for design and prediction of the on-field behavior of the piezoelectric devices (e.g., MEMS sensors and actuators and multilayer capacitors).
Dr. Bassiri-Gharb's research in the area of smart nano-systems is centered on ferroelectric nanostructures for application in environmental energy harvesting, tunable photonic crystals (TPC) and ultrasonic transducers. Cutting edge fabrication techniques, including Electron Beam Lithography and Nano-imprint, are employed for the production of the final devices. Collaborations with other groups on and off campus are in progress for piezoelectric characterization of the nanostructures and devices.
Another of Dr. Bassiri-Gharb's research topics is piezoelectric MEMS-based reflective flat panel displays and micro-stage for manipulation of nanoscale materials. Research work involves optimization of the actuating piezoelectric layers, and improved design and functionality of the other materials and components of the system. In particular, novel materials for the challenging new field of MEMS on glass are studied and implemented.
All projects involve interdisciplinary research across the fields of Mechanical Engineering, Materials Science, and Electrical Engineering.
