| Research Abstract |
New ways are developed to form nanostructures in which one or more quantum dots (QDs) are placed near a channel consisting of a single or plural quantum wires. When the structures are illuminated to generate carriers, electrons or holes are captured by QDs and affect the channel conductance, bringing forth the photoconductive functions. To form these structures, QDs were made by employing self assembly techniques, while wire structures are made by such methods as (1) the formation of multi-atomic steps on a vicinal GaAs substrate, (2) the stacking of multiple QDs, and (3) lithography.
