Mapping the surface reconstructions of MnSb(0 0 0 1) and ()

The surface reconstruction periodicities of epitaxially grown MnSb (0 0 0 1) and ( 1 1 ¯ 0 1 ) 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: ( 2 3 × 2 3 ) R30°, (2 × 2), (1 × 1) and triple domain (1 × 4). For MnSb( 1 1 ¯ 0 1 ), 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.
