Abstract

A precise nanofabrication method using a scanning tunneling microscope (STM) tip as nanoscale tweezers was devised. With the aid of surface passivation by Sb, we could form Ag nanoclusters on a Si(100) surface. It was found that self-organized Ag clusters can be selectively detached and manipulated at room temperature by field application because of the weak bonding strength between the clusters and an Sb-terminated Si surface.
