Report

Semiconductor quantum dot - a quantum light source of multicolor photons with tunable statistics

Autor: Regelman, D. V., Mizrahi, U., Gershoni, D., Ehrenfreund, E., Schoenfeld, W. V., Petroff, P. M.

Publikováno v: Phys.Rev.Lett 87, 257401 (2001)

We investigate the intensity correlation properties of single photons emitted from an optically excited single semiconductor quantum dot. The second order temporal coherence function of the photons emitted at various wavelengths is measured as a func

Report

Optical spectroscopy of single quantum dots at tunable positive, neutral and negative charge states

Autor: Regelman, D. V., Dekel, E., Gershoni, D., Ehrenfreund, E., Williamson, A. J., Shumway, J., Zunger, A., Schoenfeld, W. V., Petroff, P. M.

Publikováno v: Phys.Rev.B. 64, 165301 (2001)

We report on the observation of photoluminescence from positive, neutral and negative charge states of single semiconductor quantum dots. For this purpose we designed a structure enabling optical injection of a controlled unequal number of negative e

Report

Spectroscopy of a single semiconductor quantum dot at negative and positive discrete charge states

Autor: Regelman, D. V., Dekel, E., Gershoni, D., Ehrenfreund, E., Schoenfeld, W. V., Petroff, P. M.

We study optically single self-assembled quantum dots embedded within the wide quantum well of a mixed type quantum structure. We compare the steady state and pulsed photoluminescence spectra of these dots to those of previously studied "regular" dot

Report

Radiative Lifetimes of Single Excitons in Semiconductor Quantum Dots- Manifestation of the Spatial Coherence Effect

Autor: Dekel, E., Regelman, D. V., Gershoni, D., Ehrenfreund, E., Schoenfeld, W. V., Petroff, P. M.

Publikováno v: Solid State Communication 117 (2001) 395-400

Using time correlated single photon counting combined with temperature dependent diffraction limited confocal photoluminescence spectroscopy we accurately determine, for the first time, the intrinsic radiative lifetime of single excitons confined wit
