Meyer, and K. H. Rieder A long-standing puzzle regarding the Si(111)-2×1 surface has been solved. The surface energy gap previously determined by photoemission on heavily n-doped crystals was not compatible with a strongly bound exciton known from other considerations to exist. New low-temperature angle-resolved photoemis... [Phys. Rev. Lett. 106, 067601] Published Tue Feb 08, 2011
