Nonequilibrium spectral functions from multiterminal steady-state density functional theory
Nonequilibrium spectral functions from multiterminal steady-state density functional theory
Multiterminal transport setups allow one to realize measurements and functionalities (e.g., transistors) of nanoscale systems that are more complex than those of the simple two-terminal arrangement. Here the steady-state density functional formalism (i-DFT) for the description of transport through nanoscale junctions with an arbitrary number of leads is developed. In …
