Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Spectroscopy Quantum Dots is used to probe the quantum dot ground and excited states. Linear and nonlinear magnetoconductance measurements allow identification of individual quantum levels. Successive ground states show matched anticrossings where wavefunction characteristics are exchanged between adjacent levels. Successive excitation spectra are found to be very strongly correlated.

Chapter Three is a discussion of the different energy scales significant to the Spectroscopy Quantum Dots and their impact on the tunneling spectroscopy that we use to measure the QD energy spectrum. The raw materials of the experiment are detailed: the device fabrication, the experimental setup, experimental methods and the basic quantum dot characteristics.

Spectroscopy Quantum Dots is a sound technique to investigate quantum structures, because the wavelength of the IR light corresponds to the energy range of intraband transitions between confined states belonging to either the conduction band or the valence band. A direct measurement of the confinement energies and of the spatial symmetry of the envelope wavefunctions is possible with this technique.

The result of quantum confinement in Spectroscopy Quantum Dots is to produce a set of discrete lines in the interband absorption spectrum, as opposed to continuous bands in the bulk. Experimentally, these lines are broadened due to inhomogeneities in the sample size, shape and structure. As in the past, we consider the quantum dot to have an atomic structure like it’s bulk parent if it contains ∼ 103 atoms and below this size, the atoms begin to cluster, more akin to a molecule.
