Research Interests
Atomic excitation, resonance multiphoton ionization, collisions and laser spectroscopy; highly excited atoms, classical and quantum chaos, deposition on surfaces, scanning tunneling microscopy, nanolithography, nanoelectronics and technology, silicon nanoparticles, and Si biosensors.
Description of Current Research - Search for Quantum Chaos
Dr. Nayfeh’s group is studying the question of the existence of chaotic behavior in quantum mechanical systems whose classical analogs are known to be nonintegrable and exhibit chaotic behavior. The system that used is the interaction of low-frequency, high-power microwave radiation with one-dimensional hydrogen atoms. These atoms are prepared by laser excitation of atomic hydrogen in the presence of strong dc electric fields.
Preparation and Characterization of Porous Silicon
The project focuses on the preparation and characterization of the newly discovered optically active porous silicon. The studies include topographical, compositional, structural, optical, electrical, and chemical characterizations. These characterizations are correlated with conditions of preparation and with stability under different conditions.
