Bussolotti, F., Zhang, Z., Kawai, H., & Goh, K. (2017). A Lab-scale Spin and Angular Resolved Photoemission Spectroscopy Capability for 2D Valleytronics. MRS Advances, 2(29), 1527-1532. doi:10.1557/adv.2016.626
We report on the establishment of a new lab-scale experimental capability for Spin and Angular Resolved Photoemission Spectroscopy (SARPES) for the study of valleytronics related materials. The ARPES capabilities of the system were demonstrated by measurement on gold [Au(111)] and molybdenum disulphide (MoS2) single crystals and the full functionality of the spin detector was also verified. Experimental results are compared with theoretical modeling by ab-initio band structure calculations. We discuss the potential scope of measurement that this experimental setup affords for investigating spin-related properties (e.g. spin-orbit coupling, valley transport, etc.) in layered materials.
