Overview.
The group carriers out in-depth experimental work in the fields of nanoscale science and technology that focuses on nanofabrication, characterization and development of multifunctional electronic materials; the latter are grown by self-assembly, CVD, ALD, and hydrothermal growth techniques. Some of the laboratory focus also hones in on the intricate effects and physics governing nano-electronic, photonic and photo-voltaic devices. Past endeavors have yielded groundbreaking results, giving rise to innovative techniques and concepts in engineering nanodevices. Specifically, the work on semiconducting nanowires, quantum dots and carbon nanomaterials has paved the way for the exploration of novel device-related phenomena including thermo-electrical effects for ultra-wide broad IR sensors and energy conversion, materials for heat waste recovery, and carrier photomultiplications. The materials characterization is done routinely with HRSEM, EDX, XRD, Raman, FTIR, photoconduction spectroscopy, PL, PLE, T-dependent transport and HRTEM.
Many studies were done in collaboration with the faculty from Physics and Engineering departments at UWM, Worster Polytechnic Institute at Boston, University of Marsel, France, Arizona State University, La-Crosse University, and University of Santa-Clara, CA. Former graduates have been employed by Intel, Tesla, Meta, Texas Instruments and academic institutions in the US and abroad.
