Abstract:
Colloidal PbS quantum dots (QDs) are promising candidate materials in various optoelectronic applications including light-emitting diodes, photodetectors, and photovoltaics based on solution-processed thin-film technology. In this thesis, the stacking behavior of colloidal PbS QDs is studied in different deposition methods by using grazing-incidence small-angle X-ray scattering. These findings provide fundamental understanding for further QD based large-scaled device fabrications.
