Title: Tailoring symmetric metallic and magnetic edge states of nanoribbon in semiconductive monolayer PtS2,
Abstract: 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.
