    Spectroscopic Raman Study of Trifluoroperovskites of Ammonium Under High Pressure

    The compounds NH4MF3 (M= Mg, Zn, Co, Mn, Cd) have the cubic perovskite structure at high temperature, distorting to quasi-tetragonal symmetry at lower temperatures (fig. 1). In a previous communication /1/, some ...

    Resonant Raman Scattering in GaSb-AlSb Superlattices

    The electronic properties of GaSb-AlSb superlattices (SL) have been recently analyzed by different experimental techniques showing unambiguously the formation of electronic subbands at the Γ-point 1-2. To our kno...
