Summary form only given. In strongly confined quantum dots the size of the Hilbert space is restricted to the number of confined electronic shells. Recent progress in the fabrication of self-assembled quantum dots has resulted in the possibility of controlling precisely this number as well as the energy separation between the shells. However, the rather large inhomogeneous broadening of the dot spectra...
Summary form only given. Semiconductor quantum dots (QDs) of nanometer size are of particular interest because carriers are confined there within dimensions smaller than their de-Broglie wavelength. We present the first measurements of near field time-resolved spectroscopy via single semiconductor QD, together with a theoretical model, which quantitatively describes our measurements.
