概要
- 論文の詳細を見る
Single-atom manipulation of indium adatoms was achieved on a cleaved InAs(110) surface in a scanning tunneling microscope (STM) at low temperature. In addition to vertical manipulation by reversible STM tip--sample transfer of atoms, lateral manipulation by means of tip-induced atom hopping was achieved with an anisotropic tendency preferencially along the [001] in-plane direction by sweeping the sample bias voltage on the target adatom. Scanning tunneling spectroscopy of the adatoms assembled in a line was also achieved with an optimized tip--sample distance. The results show the molecular-like behavior of interacting adatoms.
