Near-field optical microscopy of single quantum wires

Summary form only given. Among the most promising ways to achieve the goal of fabricating one-dimensional quantum structures such as quantum wires and zero-dimensional quantum structures such as quantum dots at the same degree of perfection achieved in the two-dimensional quantum systems (quantum wells) is cleaved edge overgrowth. We report on the first low temperature near-field scanning optical microscopy study of a single, nanometer dimension, cleaved edge overgrown quantum wire fabricated by this technique.
