The general trend in modern solid state physics and technology is to make things smaller. The size of key elements in modern devices approaches the nanometer scale, for both vertical and lateral dimensions. Ultrathin layers, or quantum wells, had already gained broad acceptance for applications in micro- and optoelectronics by the 1980s. However, the development of het erostructures with lower dimensionality (quantum wires, where carriers are confined in two directions and move freely in one, and quantum dots, where carriers are confined in all three directions) took longer. It became clear that quantum wire and dot structures constitute the utmost technological chal lenge, whilst providing enormous advantages. At the beginning of the 1990s, a few outstanding discoveries concern ing self-organization phenomena at crystal surfaces for direct fabrication of nanostructures led to a change in the major paradigms of semiconductor physics and technology. This new approach in epitaxy enables fast parallel fabrication of large densities of quantum dots or wires for almost unlimited material combinations and has become the basis for a powerful new branch of nanotechnology. Quantum dots, coherent inclusions in a semiconductor ma trix with zero-dimensional electronic properties persistent up to room tem perature, have demonstrated fascinating physical properties and given birth to a novel generation of optoelectronic devices and systems.
