This course will explore the physical properties of quantum wells, rods, wires, dots, and related nanostructures, including carbon nanotubes. Quantum-confinement effects in semiconductor nanostructures exert strong influences on their electronic structures and absorption/emission behavior. The theoretical and experimental bases for quantum-confinement effects, which are of considerable fundamental and applied interest, will be developed. Carbon nanotubes and other nanowire systems are currently under evaluation for use in nanoelectronic circuits and devices. Such systems exhibit fascinating electrical-transport behavior, which will be reviewed. The synthesis and fabrication of quantum nanostructures will also be discussed. Prereqs: Chem 461 and Chem 465, or permission of the instructor.
