The effect of width on graphene nanoribbon density of state under uniaxial strain

Abstract

In this paper, an analytical density of states modeling and simulation study was performed for 3m, 3m+1 and 3m+2 armchair-edge graphene nanoribbon under smaller tensile uniaxial strain. It has been discovered that the irregular variation in DOS as a function of energy when the tensile uniaxial strain is increased from 0% to 3%. In addition, despite to be reduced in terms of energy gap, 3m+1-AGNR is reported to have higher DOS compared to the other families of AGNR while the energy gap opening is confirmed to behave according to its family's behavior.
