Abstract

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 Al4(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.
