Investigating the Growth of Highly Ordered Thin Films of Two-Dimensional Materials on Metallic Films Supported by Insulating Substrates

The novel two-dimensional (2D) materials, such as graphene, MoS2, silicence, Bi2Se3, and Bi2Te3,etc., have drawn tremendous interests because of their exotic structural and electronic properties.Although it has been demonstrated successfully to construct nanodevices based on 2D materials inseveral cases, it remains great challenges to obtain large-area high-quality thin films of 2D materialsroutinely for mass production. In this proposal, we plan to develop novel and low-cost methods togrow high-quality thin films of 2D materials on insulating substrates, i.e. mica and sapphire. Ifexecuted successfully, this proposal will deliver the key knowledge to grow large-area thin films of 2Dmaterials with much less defects and domain boundaries on insulating substrates, and will contributesignificantly in the development of the 2D-material-based nanoelectronics.
