Phys. Rev. Lett. 53, 1954–1957 (1984)Comparison between the Electronic Structures of GaAs(111) and GaAs(1―1―1―) from Angle-Resolved PhotoemissionReceived 30 July 1984; published in the issue dated 12 November 1984 Angle-resolved photoemission spectra have been measured for the polar (1―1―1―) and (111) surfaces of GaAs. The results show definitively that although both faces exhibit a (2×2) reconstruction, the local geometries of the unit cells must be distinctly different. © 1984 The American Physical Society URL:
