Transport properties of armchair graphene nanoribbons under uniaxial strain: A first principles study

• Effect of strain on transport properties of AGNRs is studied using DFT calculations.
• Transport properties of AGNRs are very sensitive to uniaxial strain.
• Electron mobility of 5-AGNR is up to 38.5×104cm2/Vs at an elongation of 6.

In this work, transport properties of armchair graphene nanoribbons (AGNRs) under uniaxial strain are considered using density functional theory. We found that carrier mobility of AGNRs depends strongly on uniaxial strain. The electron mobility of 5-AGNR is up to 38.5×104cm2/Vs at an elongation of 6%. However, the dependence of the effective mass of electrons and holes of AGNR on uniaxial strain can almost be described by the same function and their effective masses coincide at an elongation of 10%. The sensitivity to strain of the transport properties of AGNRs opens many ways for applications in nanoelectromechanical devices.
