Abstract

The two-fold surface of the icosahedral quasicrystal Al 70.2Pd 21.5Mn 8.3 prepared in UHV has been studied with LEED and STM. Two phases are observed: a quasiperiodic phase, in agreement with previous work, and a periodic phase tentatively identified as orthorhombic. Copper deposition on the two-fold surface leads to a multilayer exhibiting a quasiperiodic LEED pattern.
