Mapping the surface reconstructions of MnSb(0 0 0 1) and (11¯01)

The surface reconstruction periodicities of epitaxially grown MnSb (0 0 0 1) and (11¯01) have been determined under a range of beam fluxes and substrate temperatures using reflection high energy electron diffraction. A number of previously unreported surface reconstructions were observed. On MnSb(0 0 0 1), reconstructions ordered from Mn rich to Sb rich are: (23×23)R30°, (2 × 2), (1 × 1) and triple domain (1 × 4). For MnSb(11¯01), distorted (4 × 2) and simple (1 × 2) surface symmetries occur. The common (0 0 0 1) surface reconstructions of MnAs and MnSb are briefly reviewed and discussed.
