Abstract:The carrier mobility of two-dimensional tetragonal carbon allotrope (T-CA) from porous graphene is investigated by first-principles calculations. T-CA can be constructed from divacancy and Stone–Thrower–Wales defects from graphene. T-CA is a direct semiconductor with a band gap of 0.4 eV at ${\it \Gamma}$ point. T-CA possesses a high carrier mobility of the order of 10$^{4}$ cm$^{2}$V$^{-1}$s$^{-1}$. As our study demonstrates, T-CA has potential applications for next-generation electronic materials.
