Abstract

The family of transitionmetal dichalcogenides offer a unique platformfor electronic and optical tunability due to the sensitivity to their dimensional configuration, edge terminations, and varying crystal phases. In this thesis we focus on structures based on the transition metal dichalcogenides MoS2 and WS2. We study how different crystal phases and edge structures of these two transition metal dichalcogenides affect their optical, electronic, and structural behaviour with the use of electron energy loss spectroscopy, energy-dispersive X-ray spectroscopy, and high resolution spatial imaging in the transmission electron microscopy in order to carry out our studies. When possible, we complement our experimental studies with ab initio calculations.
