The transfer Length Method is a well–established experimental technique to characterize the contact resistance in semiconductor devices. However, its dependability is questioned for metal–graphene contacts. We investigate in–depth the statistical error of the extracted contact resistance values and we devise strategies to limit such error and to obtain reliable results. The method has been successfully applied to samples with different contact metals.

Abstract
The transfer Length Method is a well–established experimental technique to characterize the contact resistance in semiconductor devices. However, its dependability is questioned for metal–graphene contacts. We investigate in–depth the statistical error of the extracted contact resistance values and we devise strategies to limit such error and to obtain reliable results. The method has been successfully applied to samples with different contact metals.File in questo prodotto:
