Two-Dimensional Semiconductors Beyond Graphene

Certain novel aspects of the electronic bandstructure and the charge-transport properties of 2D semiconductor crystals are the drivers for novel electronic device ideas in semiconductor physics. In my presentation, I will give an introduction to these aspects of transport properties and carrier dynamics in 2D crystals. Both low-field 'linear' transport and high-field transport with strong electron-phonon interactions will be discussed. Then, novel devices that exploit the unique features of 2D semiconductors will be described, and experimental progress towards their realization will be presented. The talk will make an attempt to connect the physics of 2D semiconductors to realistic near-term and future applications.
