Beschreibung:
  • We demonstrate an all‐electrical prepartion and detection of many‐particle spin states in self‐assembled QDs. The excited states of the first three ‘QD elements’ are measured, i. e. the degenerate s‐, p‐ and d‐shells of QD‐Hydrogen (one electron), the many‐particle triplet and singlet states of QD‐Helium (two electrons) and the many‐particle states of QD‐Lithium (three electrons). Comparison with exact diagonalization calculations fully accounting for the effects of Coulomb interaction enables us to reveal unambiguously the different charge and spin configurations.
