Abstract for Presentation

Single-crystalline 2D semiconductor growth and device technology

 

 

   2D transition-metal dichalcogenide semiconductors are promising candidates in future electronics due to unmatched device performance at atomic limit and low-temperature heterogeneous integration. In this talk, I will present our recent advances in this area. The main topics include wafer-scale single-crystal epitaxial growth, uniform bi-layer material growth, dielectric integration and Ohmic contact, and heterogeneous integration with mainstream technology. These advances clearly demonstrate the promise of 2D semiconductors in next-generation electronic and optoelectronic applications.
