Abstract:	摘要： ► We investigate Al(1 0 0) with high-resolution angle-resolved photoelectron spectroscopy. ► Many features in the surface band structure are confirmed for the first time. ► Three surface states are identified and studied in details. ► Our study provides high-quality data that serve as reference for future investigations. From an examination of the Al(1 0 0) surface band structure with high-resolution angle-resolved photoelectron spectra, we identified three surface states. Features in the surface band structure predicted theoretically were confirmed experimentally, including the dispersion of the surface state within the narrow band gap centered at X ¯ , an avoided crossing between two surface states along Γ ¯ X ¯ , and the dispersion of the surface state within the symmetry gap along Γ ¯ M ¯ . The electron–phonon coupling strength of the surface state at Γ ¯ was determined. Our results indicate that there is no thermally induced defect on Al(1 0 0) from 90 to 420 K. Our photoemission data serve as reference for future investigation and motivate re-examination of many systems with contemporary photoemission instruments. 出版者： Elsevier B.V 出版日期： 2012 出處： Journal of electron spectroscopy and related phenomena, 2012, Vol.184 (11), p.551-555 版權： 2011 Elsevier B.V. 識別號： ISSN: 0368-2048 識別號： EISSN: 1873-2526 識別號： DOI: 10.1016/j.elspec.2011.09.003
