Rev. B 76 153305), we have performed spin- and angle-resolved photoemission measurements at ~120 K on ultrathin Bi films grown on a Si substrate, focusing on the split surface-state bands near the Fermi level. We found clear experimental evidence that these states show Rashba-type spin-split behavior near \barΓ, but the splitting is lost near \barM where they overlap with the bulk band projection. This can be explained as a change in the origin of the splitting from a Rashba effect to a parity effect as revealed by ab initio calculations.This work has been supported by Grants-In-Aid from the Japanese Society for the Promotion of Science.Peer reviewedInstitute of Physics Publishing200820082008info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_65012280260 bytesapplication/pdfhttp://hdl.handle.net/10261/8465reponame:DIGITAL.CSIC.
