Abstract
A team of researchers have conducted a study to demonstrate the concentration of atomic wires and the impact of interaction between the absorbate, substrate, and its electronic consequences on platinum (Pt) chains on germanium Ge(001) surface formed by self-organization. The study demonstrated that after absorption and high temperature of around 0.25 Pt monolayers, a regular array of Pt chain and single atomic chains were observed on the β-terraces. It was observed that these chains were formed by replacing Ge atoms of the first layer with Pt. These chains were arranged as Pt dimers along the chain axes at room temperature, while increasing its periodicity upon cooling below 77 K. The increase in periodicity was accompanied by a significant reduction of metallicity.
