“…Adding the composite element, either B and N, can also lead to FM states, thanks to the non-paired p-electrons in these elements. The theoretically predicted result was verified through X-ray magnetic circular dichroism (XMCD) [75]. Later, weak FM was proven on a carbon-doped BN nanosheet in line with the theoretical prediction [76].…”

Pioneering explorations of the two-dimensional (2D) inorganic layered crystals (ILCs) in electronics have boosted low-dimensional materials research beyond the prototypical but semi-metallic graphene. Thanks to species variety and compositional richness, ILCs are further activated as hosting matrices to reach intrinsic magnetism due to their semiconductive natures. Herein, we briefly review the latest progresses of manipulation strategies that introduce magnetism into the nonmagnetic 2D and quasi-2D ILCs from the first-principles computational perspectives. The matrices are concerned within naturally occurring species such as MoS 2 , MoSe 2 , WS 2 , BN, and synthetic monolayers such as ZnO and g-C 2 N. Greater attention is spent on nondestructive routes through magnetic dopant adsorption; defect engineering; and a combination of doping-absorbing methods. Along with structural stability and electric uniqueness from hosts, tailored magnetic properties are successfully introduced to low-dimensional ILCs. Different from the three-dimensional (3D) bulk or zero-dimensional (0D) cluster cases, origins of magnetism in the 2D space move past most conventional physical models. Besides magnetic interactions, geometric symmetry contributes a non-negligible impact on the magnetic properties of ILCs, and surprisingly leads to broken symmetry for magnetism. At the end of the review, we also propose possible combination routes to create 2D ILC magnetic semiconductors, tentative theoretical models based on topology for mechanical interpretations, and next-step first-principles research within the domain.

“…Moreover, vacancies in BN can also induce interesting magnetic properties. It has been predicted that the B vacancy defect can induce a spin polarization in the nearest three N atoms while the results on the N vacancy show discrepancies . The spontaneous magnetization induced by boron vacancy or divacancy can be further switched by biaxial strain …”

Boron nitride (BN) structures are featured by their excellent thermal and chemical stability and unique electronic and optical properties. However, the lack of controlled synthesis of quality samples and the electrically insulating property largely prevent realizing the full potential of BN nanostructures. A comprehensive overview of the current status of the synthesis of two-dimensional hexagonal BN sheets, three dimensional porous hexagonal BN materials and BN-involved heterostructures is provided, highlighting the advantages of different synthetic methods. In addition, structural characterization, functionalizations and prospective applications of hexagonal BN sheets are intensively discussed. One-dimensional BN nanoribbons and nanotubes are then discussed in terms of structure, fabrication and functionality. In particular, the existing routes in pursuit of tunable electronic and magnetic properties in various BN structures are surveyed, calling upon synergetic experimental and theoretical efforts to address the challenges for pioneering the applications of BN into functional devices. Finally, the progress in BN superstructures and novel B/N nanostructures is also briefly introduced.

“…[24] Yang et al investigated adatoms and defect-induced magnetism in h-BN. [26] Ta ng and co-workers predicted that C-doped half-bare zigzag BN nanoribbons show magnetism as well as half-metallicity. [34] Intrinsic magnetism was induced in BN nanotubes by their open ends as well as C-doping.…”

Metal‐free half‐metallicity is the subject of intense research in the field of spintronics devices. Using density functional theoretical calculations, atom‐thin hexagonal boron nitride (h‐BN)‐based systems are studied for possible spintronics applications. Ferromagnetism is observed in patterned C‐doped h‐BN systems. Interestingly, such a patterned C‐doped h‐BN exhibits half‐metallicity with a Curie temperature of approximately 324 K at a particular C‐doping concentration. It shows half‐metallicity more than metal‐free systems studied to date. Thus, such a BN‐based system can be used to achieve a 100 % spin‐polarised current at the Fermi level. Furthermore, this C‐doped system shows excellent dynamical, thermal, and mechanical properties. Therefore, a stable metal‐free planar ferromagnetic half‐metallic h‐BN‐based system is proposed for use in room‐temperature spintronics devices.
