graphene sheet resistivity

R=Rs W/L ,where Rs is the sheet resistivity. and it is a constant Now for graphene, as W decreases, R should also decrease(because Rs is constant).But R increases ,they say no. of conducting channels decreases with W. So does it mean Rs is not a constant for graphene or any other ballistic material???

    Hi, I believe Rs increases as W decreases. Line-edge roughness increases as W increases as well in addition to the reduction of number of conducting modes. In short, Rs is proportional to rho(resistivity) and 1/mobility and mobility decreases as W decreases. Therefore, Rs is not constant as the width of graphene reduces down to several nanometers.
