1Abstract
We present scanning tunnelling microscopy (STM) studies of the fivefold surface of icosahedral (i) Ag-In-Yb quasicrystals grown under different conditions. The sample grown at a slower rate is found to exhibit impurity phases on the surface, whereas a faster growth rate yields a sample with a structurally perfect surface
