Research Abstract

We have succeeded in well-controlled fabrication of one-dimensional structures by self-organization of dosed metal atoms and hydrocarbon molecules on vicinal surfaces of metal single crystals where parallel straight steps are arranged periodically. The crystallographic features, electronic structures, and magnetism of the one-dimensional structures have been investigated, which are completely different from physical properties of three-dimensional bulks of the same materials. We are searching for a new substance, which shows interesting nature in one-dimensional shape.
