Surface engineering of phosphorene nanoribbons by transition metal heteroatoms for spintronics

Abstract

Modulating the electronic and magnetic properties of phosphorene is important for fabricating multi-functional electronic and spintronic devices.

Ultra‐Narrow Phosphorene Nanoribbons Produced by Facile Electrochemical Process

“…PNRs are also predicted to host several exotic states [ 18 ] and may play an important role in several fundamental areas of condensed matter physics. In addition to topologically‐protected edge states, [ 19 ] some of the other exotic properties predicted for these structures include spin‐density waves, [ 20 ] strain‐dependent antiferromagnetism, [ 21 ] and half‐metallic behavior [ 22 ] which could be relevant to spintronics applications, [ 23 ] the spin‐dependent Seebeck effect, [ 24 ] that could help to advance thermoelectric technologies, and a large singlet–triplet splitting, [ 18 ] that could potentially be relevant to quantum information. The crossed Andreev reflection [ 25 ] has also been recently investigated theoretically in structures based on such nanoribbons.…”

Electric-Field Control in Phosphorene-Based Heterostructures

“…The other significant effect concerns the induced spin-polarized currents without employing any extrinsic magnetic impurities. Typically, a relatively large spin polarization can be observed in quasi-1D nanoribbons of different graphene-like materials, including phosphorene, with embedded TM atoms [ 25 , 38 , 39 , 40 ]. However, including TMs can present deficiencies concerning the further processing of the nanoribbons, and clustering effects of the TM atoms can occur.…”

A BC2N/blue phosphorene heterostructure as an anode material for high-performance sodium-ion batteries: first principles insights

“…Analogous to graphene, 20 2-D Black-P, named black phosphorene (Black-Pn), 15,[21][22][23][24] has been identified as a stable form of phosphorus and has been the subject of intense studies in many applications, such as photocatalysis, gas sensing, hydrogen storage, and spintronics. [25][26][27][28] First-principles computations revealed that Black-Pn displays high theoretical capacities and rapid ion mobilities when used as an NEM in metal-ion batteries. [29][30][31] It has also been demonstrated that the Black-P/ graphene heterostructure possesses advantageous parameters for NIBs.…”
