AbstractA comparison of calculated and experimental temperature variation of elastic constants were used to predict types of oxygen—vacancy dopant clusters in yttria stabilised cubic zirconia, which serves as an electrolyte in solid oxide fuelcells. Such clusters were incorporated in supercells set up for molecular dynamics studies, where oxygen transport properties were investigated at concentrations of 9.4 and 24 mol % of yttrium oxide and up to 1600K.

It has been realized lately that disorder, primarily in the form of oxygen vacancies, cation stoichiometry, atomic inter-diffusion and antisite defects, has a major effect on the electronic and transport properties of a 2D electron liquid at oxide hetero-interfaces – the first and the last being the two key players.

We have studied the transport properties of ordered and disordered doped metallic nanotubes. We have presented these properties in periodic chemically metallic nitrogen doped metallic nanotubes. Transport properties with long range correlation have been studied using the Green’s function formalism in the frame work of the tight binding approach with effective parameters. Resonant conduction behaviour and ballistic transport have been demonstrated for particular positions of the dopant. These doping patterns have been shown to preserve the Bloach like transport properties and then to avoid Anderson localisation. The conductance response was almost changed because one of the two conductance channels remains true for both armchair and chiral nanotubes. These result reproduce the electronic properties of periodic nitrogen doped graphene. The present result has been drawn for specific chemical substitution of carbon atoms by nitrogen. These remain qualitatively valid for other local modifications of the nanotube by other chemical species by covalent or noncovalent functionalization. The energy of the quasi bound state depend on the specific local modification. We have shown that both axial and screw periodicities gave rise to such a behaviour and that specific disorder preserve their ballistic transport in doped metallic carbon nanotube.
