An Experimental and Theoretical Study of the Electronic Structure of the W (111) Surface
We report results of synchrotron angular resolved photoemission experiments from W (111) together with a theoretical analysis of the data. For normal emission several different surface sensitive features are found depending on the s or p polarization of the incident radiation. The symmetry assignements derived from this polarization dependence are compared with theoretical results based on a tight binding calculation of the electronic structure of a 16 layers thick slab. The same analysis is extended to offnormal data collected in the mirror plane.
