Abstract

The two-fold surface of the icosahedral quasicrystal Al70.2Pd21.5Mn8.3 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 orthorhom- bic. Copper deposition on the two-fold surface leads to a multilayer exhibiting a quasiperiodic LEED pattern.
