Surface study of the (100) and (010) faces of the quasicrystal approximant Al-4(Cr,Fe)
Zeitschrift Fur Kristallographie 224(1-2): 13-15
Low-energy electron diffraction (LEED) and scanning tunneling microscopy (STM) results are used to study the pseudo-6-fold nature of the (100) surface of the orthorhombic quasicrystal approximant Al-4(Cr, Fe). LEED patterns are also presented from the pseudo-10-fold (010) surface of this material. In each case the results are compared with the known bulk structure of this complex metallic alloy.
