Epitaxial Growth and Properties of 2D Monolayer PtSe2 & In-plane Heterostructures*
11:15 AM–11:27 AM
In this talk, I will report the fabrication and properties of novel 2D materials like semiconducting transition-metal-dichalcogenide monolayer PtSe2  and its in-plane 1T/1H heterostructure with atom-shape interface , as well as superconductor transition-metal-trichalcogenide (HfTe3), grown by direct selenization/tellurization of the Pt/Hf substrate. Their application exploring in nanoelectronics and valleytronics will also be introduced. In addition, the stacking heterolayers based on several these kinds of 2D materials, for instance, a superconductor-topological insulator layered heterostructure (with an HfTe3/HfTe5 layered configuration) for Majorana bound states will be briefly presented [4,5]. We expect that these materials will show intriguing physical property and promising potential applications in nanoscale devices.
