(Invited) GaAs Quantum Dots in Gap Nanowires: Growth and Luminescence

Nanowires are rod or whisker-like structures with length on the order of microns and diameter from tens to hundreds of nanometers. They represent a new class of three-dimensional materials, and the next step in the evolution of conventional two-dimensional thin films, quantum wells, or heterostructures. Nanowires are typically fabricated by the assistance of foreign metal catalysts, such as Au, that collect deposited material, resulting in …
