Abstract

Electrical and magnetic properties of narrow phosphorene nanoribbons are theoretically studied. Within the Hubbard-type Hamiltonian combined with the self-consistent calculation method, the following topics are considered: spin- dependent electrical conductance, electronic thermal conductance, Seebeck coefficient and thermoelectric power factor. The emphasis is put on the modification of these physical quantities due to the appearance of antidots (nanopores). It is shown that the crucial role is played by the magnetic moments occurring both on external ribbon-edge atoms as well as on internal nanopore-edge atoms arranged in a zigzag way. Noteworthy, in case of structures with parallel magnetic configurations on the external edges, the systems show half-metallic behavior promising for expected spintronic applications.
