2D semiconductors are unique optical materials that exhibit the characteristics of molecules as well as bulk semiconductors. Their strong excitonic character and tunability make them attractive for unconventional electro-optic devices.
Electrons travelling within a 2D crystal lattice carry multiple quantum degrees of freedom that can be manipulated by external signals. We utilize magneto-transport measurements to probe the dynamics of these information carriers.
Integration of intelligently designed nanostructures is key to the development of practical devices with tailored functionalities. We develop methods to grow and implement 2D materials into atomically defined architectures.
Layered compounds occur in various polytypes and polymorphs with distinct electronic properties. We investigate phase transformation mechanisms with the aim to developing catalytically active materials and switching devices.
Some of the recent developments of the field are summarized in our Review and Perspectives articles:
