Engineering enhanced thermoelectric properties in zigzag graphene nanoribbons
We theoretically investigate the thermoelectric properties of zigzag graphene nanoribbons in the presence of extended line defects, substrate impurities, and edge roughness along the nanoribbon’s length. A nearest-neighbor tight-binding model for the electronic structure and a fourth nearest-neighbor force constant model for the phonon bandstructure are used. For transport, we employ quantum me...
متن کاملThermoelectric Properties of Doped Zigzag Silicene Nanoribbons
Thermoelectric properties of silicene nanoribbons doped with magnetic impurity atoms are investigated theoretically for both antiparallel and parallel orientations of the edge magnetic moments. Spin density distribution and transport parameters have been determined by ab-initio numerical methods based on the density functional theory. Doping with magnetic atoms considerably modi es the spin den...
متن کاملTransport Gap Engineering in Zigzag Graphene Nanoribbons
Graphene, a recently discovered form of carbon, has received much attention over the past few years due to its excellent electrical, optical, and thermal properties [1]. With an extraordinary carrier mobility and high current density [2], graphene's application in electronic devices is promising. As a zero bandgap material, pristine graphene cannot be used as a semi-conducting channel in transi...
متن کاملEnhanced Thermoelectric Figure of Merit in Edge Disordered Zigzag Graphene Nanoribbons
We investigate electron and phonon transport through edge disordered zigzag graphene nanoribbons based on the same methodological tool of nonequilibrium Green functions. We show that edge disorder dramatically reduces phonon thermal transport while being only weakly detrimental to electronic conduction. The behavior of the electronic and phononic elastic mean free paths points to the possibilit...
متن کاملEnhanced half-metallicity in edge-oxidized zigzag graphene nanoribbons.
We present a comprehensive theoretical study of the electronic properties and relative stabilities of edge-oxidized zigzag graphene nanoribbons. The oxidation schemes considered include hydroxyl, lactone, ketone, and ether groups. Using screened exchange density functional theory, we show that these oxidized ribbons are more stable than hydrogen-terminated nanoribbons except for the case of the...
