Semiconductor Quantum Wires
This lecture addresses two-dimensional quantum confinement in colloidal semiconductor nanowires (CdSe, InP, InAs, GaAs, CdTe, etc.) having diameters in the strong confinement regime. The quantum wires are grown by solution-phase organometallic reactions analogous to those employed in the synthesis of the best-quality colloidal quantum dots. Wire growth is effected through the use of nanometer-sized metallic catalyst particles. The spectroscopic properties of the wires are determined, and compared to simple theoretical models to confirm two-dimensional quantum confinement in the wires.
