Surface structures and electronic states of clean and (NH4) 2Sx-treated InAs (111) A and (111) B
S Ichikawa, N Sanada, N Utsumi… - Journal of applied physics, 1998 - pubs.aip.org
The surface structures, unoccupied and occupied electronic states, and chemical states of
surface atoms for clean and (NH4) 2Sx-treated InAs (111) A and (111) B surfaces have been
studied using low-energy electron diffraction (LEED), inverse photoemission spectroscopy
(IPES), and (x-ray and ultraviolet) photoemission spectroscopy (PES). Thermal stability of
the treated surfaces upon annealing in an ultrahigh vacuum is also investigated. A diffuse
(11) LEED pattern appears for the treated-(111) A and-(111) B surfaces annealed at 230 …
