Dynamical stability and electronic structure of β-phosphorus carbide nanowires

Abstract

In this work, [Formula: see text]-phosphorus carbide 1D nanowires (PCNWs) are investigated in the framework of density functional theory. The dynamical stability of the considered [Formula: see text]-PCNWs at 300[Formula: see text]K is verified using ab initio molecular dynamics calculations. According to the results on the band structure calculations, [Formula: see text]-PCNWs can be semiconductors, semimetals or metals depending on their size and form. Thus, owning to their unique shape and high tunability of electronic properties, [Formula: see text]-PCNWs may be used in optical and photovoltaic nanodevices.
