  By applying tight binding model, we investigate the electronic and transport
properties of randomly distributed Stone-Wales (SW) defects on an armchair
graphene nanoribbon (AGNR). We use four different functions, as distribution
functions, to generate our SW defected nanoribbons. It is found that defect
density can have a major effect on the conductance of our defected system,
whilst other configurations such as defect orientation will contribute less. In
our investigations. some special geometries are found, which shows interesting
electronic and transport properties. These special cases along the other data
provided can be used to engineer band gap, electronic properties and transport
properties of graphene nanoribbons to meet the desired purpose.
