One-dimensional chains of gold clusters on the surface of highly oriented pyrolytic graphite

摘要

We have investigated the growth of gold nanoclusters on the surface of highly oriented py- rolytic graphite in ultrahigh vacuum. Studies of ultrahigh vacuum scanning tunneling microscopy re- vealed that the size distribution of gold clusters was very narrow and quasi-one-dimensional chains of gold nanoclusters of approximately 2 nm diameter were produced after being annealed at 74 deg.C.
