At the SPIN (Spins and Photons in Nanostructures) Lab, we focus our research on the experimental study of quantum optoelectronic and quantum transport phenomena in reduced dimensionality systems to develop future quantum technologies. We perform experiments on novel 2D materials such as transition metal dichalcogenides (MoS2, WSe2, etc.) and Van der Waals heterostructures made with them as well as 2D quantum wells based on GaAs/AlGaAs heterostructures. We further reduce the dimensionality by fabricating quantum devices which include 1D channels and 0D quantum dots.
