Tailoring symmetric metallic and magnetic edge states of nanoribbon in semiconductive monolayer PtS2

Fabrication of atomic scale of metallic wire remains challenging. In present work, a nanoribbon with two parallel symmetric metallic and magnetic edges was designed from semiconductive monolayer PtS2 by employing first-principles calculations based on density functional theory. Edge energy, bonding charge density, band structure and simulated STM of possible edges states of PtS2 were systematically studied. It was found that Pt-terminated edge nanoribbons were the relatively stable metallic and magnetic edge tailored from a noble transition metal dichalcogenides PtS2. The nanoribbon with two atomic metallic wires may have promising application as nano power transmission lines, which at least two lines are needed.
