Linear conductances of gated graphene structures with selected connectivity

Linear conductances of gated graphene structures with selected connectivity

The ratio of conductances through carbon-ring based molecules are calculated for various  positions  of  source-drain  electrode  leads  on  the  molecule.    These  ratios are usually integers – the so-called magic numbers.  We find that deviations of the magic number ratios are either zero or quad...

Description
Summary:The ratio of conductances through carbon-ring based molecules are calculated for various  positions  of  source-drain  electrode  leads  on  the  molecule.    These  ratios are usually integers – the so-called magic numbers.  We find that deviations of the magic number ratios are either zero or quadratic in ratios of tight-binding model parameters.
