Dr. Bedair currently investigates semi-conductor materials and devices including novel growth techniques such as atomic layer epitaxy, laser-assisted diposition, molecular beam epitexy and chemical vapor diposition. He also studies optical, electrical and structural properties of semiconductors, epitaxial insulators and quantum well structures. Optical and microwave devices such as detectors, wave guides, solar cells, light emitting diodes, semiconductor light bulbs and modulation doped field effect transistors are currently considered in Dr. Bedair's lab.
