Quantum Dot Heterostructures Dieter Bimberg, Marius Grundmann and Nikolai N. Ledentsov Institute of Solid State Physics, Technische Universitat Berlin, Germany Quantum dots are nanometer-size semiconductor structures, and represent one of the most rapidly developing areas of current semiconductor research as increases in the speed and decreases in the size of semiconductor devices become more important. They present the utmost challenge to semiconductor technology, making possible fascinating novel devices. This important new reference book focuses on the key phenomena and principles. Chapter...

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...

Reducing the size of a coherently grown semiconductor cluster in all three directions of space to a value below the de Broglie wavelength of a charge carrier leads to complete quantization of the energy levels, density of states, etc. Such quantum dots are more similar to giant atoms in a dielectric cage than to classical solids or semiconductors showing a dispersion of energy as a function of wavevector. Their electronic and optical properties depend strongly on their size and shape, i.e. on their geometry. By designing the geometry by controlling the growth of QDs, absolutely novel...
