First principles design of multifunctional spintronic devices based on super narrow borophene nanoribbons.

ABSTRACT: Borophene, as a new material with various configurations, has attracted significant research attention in recent years. In this study, the electronic properties of a series of χ-type borophene nanoribbons (BNRs) are investigated using a first-principles approach. The results show that the width and edge pattern of the nanoribbons can effectively tune their electronic properties. Notably, a super-narrow χ-type BNR is found to be ferromagnetic and exhibits half-metallic properties. Based on these findings, a χ-type borophene nanojunction is proposed, and its spintronic transport properties are investigated using the non-equilibrium Green's function method combined with density functional theory. The results demonstrate that the nanojunction exhibits excellent spin filtering capabilities unde
