Coherent optical spectroscopy and manipulation of single quantum dots

摘要: Publisher Summary This chapter starts with an overview of semiconductor quantum dots (QDs). Excitons and biexcitons, their importance to the optical response single QDs, are briefly discussed. A simple model used successfully explain many experiments in various QD systems is Semiconductor QDs represent simplest nanostructures where 3D confinement imposed on electron hole motion leads strongly modified electronic properties. The most remarkable feature that makes so desirable for future generations optical, logic devices fully quantized atomic-like energy structure (although they normally contain 103–106 atoms). reviews discusses physics based spectroscopy performed at level. discussion focused a particular gallium arsenide (GaAS) system, which experimental efforts authors reside..Coherent preparation manipulation states among core elements utilizing phase, such as computers optically driven QDs. Experiments show exciton biexciton can be coherently manipulated similar way atoms.
