My work is focused on colloidal semiconductor nanocrystals (NCs), particles small enough that their opto-electronic properties can be controlled by varying the size, shape and material composition. This is made possible due to quantum confinement of electrons and holes within the NCs; they are therefore also referred to as quantum dots.
After the PhD, I turned to the investigation of the opto-electronic band structure and stimulated emission properties of CdSe-based quantum dots and quantum rods (2009-2011). The project was executed at Ghent university and the IBM Zurich Research Laboratory, Switzerland. In January 2012 I joined the Italian Institute of Technology (IIT), where I combined materials science and optical spectroscopy to design new photonic NCs.
