The low-dimensional quantum states and their atomic-scale engineering in elemental chalcogens and chalcogenides
When reduced to lower dimensions, materials exhibit diverse electronic, optical, and magnetic properties. Their tunable physical properties under multiple external fields hold significant promise for fundamental research and future technological applications. By understanding the microscopic mechanisms that govern these macroscopic properties, we can guide the design and fabrication of materials for functional applications. Here, I will introduce several MBE-grown low-dimensional quantum materials and the atomic-scale tailoring of their properties, including elemental Te with helical crystal structure, transition metal telluride, and superconducting iron selenide.
