For the treatment of increasingly complex cardiac arrhythmias, new catheter designs as well as alternative energy sources are constantly being developed. However, there is presently no in vitro method available for assessment of the temperature chang

Using a Four-Wave-Mixing (FWM) experiment in backward-scattering geometry the coherent dynamics of the quadrupole polarization associated with excitonic molecules is studied in bulk CdSe. By analyzing the FWM signal at negative delay times and exploi

In epitaxially grown CdSe quantum dots the LO-phonon coupling is studied by analysing phonon-assisted recombination of a single zero-dimensional exciton. Due to the microscopic disorder of Cd-ions the observed line shape of the LO-phonon replica show

Migration enhanced epitaxy of CdSe islands on ZnSe and their optical and structural characterization
Publikováno v:
Microelectronic Engineering. :701-705
Formation of self-assembling CdSe islands on ZnSe has been achieved using Migration Enhanced Epitaxy (MEE). Atomic Force Microscopy (AFM) images of uncapped samples show spherical islands with a diameter-to-height ratio of 4:1, which is not yet an un
