Abstract:
The electronic properties of aromatic amino acids physisorbed on graphene are investigated in view of establishing if carbon nanotube transconductance sensors can respond to this type of chemical stimuli. Several conclusions are drawn regarding both the sensitivity and selectivity of amino acid nanotube sensors based on results presented in the first part of this paper, while a series of methods for simplifying a self-consistent Hamiltonian down to a model, enabling accurate conductance calculations for systems of considerable size will be introduced in the second part.
