“…In addition to charge transport, the devices based on spin transport might be a possible solution. In this regard, 2D materials based on transition metal atoms, such as transition metal disulfides (TMDs) [1–8], transition metal carbides (TMCs) [9–14], transition metal halides (TMHs) [15–23], transition metal phosphides (TMPs) [24–26], transition metal borides (TMBs) [27–33], and so forth have become potential candidates with intrinsic magnetism for spin transport applications.…”

Developing 2D materials with intrinsic magnetism is an essential issue owing to their wide potential applications in spintronics. Here, a type of transition metal tetraborides, TMB4, (TM = TiCo) monolayers were systematically investigated by employing first principles calculations. Our results showed that the predicted structures hold buckled motif, ultrahigh stability and large magnetic anisotropy energy. It is revealed that CrB4, MnB4, and FeB4 monolayers are robust ferromagnetism, differently, TiB4, VB4, and CoB4 monolayers are stable anti‐ferromagnetism. Based on the Monte Carlo simulation, the critical temperatures of these magnetic systems are around 177–755 K. Most importantly, CoB4 monolayer is confirmed to be an antiferromagnetic semiconductor with out‐of‐plane magnetic easy axis and out‐of‐plane piezoelectricity with large piezoelectric stress coefficients. Our study suggests that the 2D TMB4s hold promising applications for spintronic devices and piezoelectric devices.

“…It is not difficult to understand that heavy quark systems are more likely to have attraction and form bound states in the molecular state picture due to the reduction of the kinetic of the systems resulting from the large masses of the heavy quark systems. Up to now, some theoretical investigations have been performed to look for possible bound states composed of two heavy baryons or a pair of heavy baryon and antibaryon within the constituent quark model [24][25][26], one-boson-exchange model [27][28][29], a quark level effective potential [30], a chromo-magnetic interaction model [31].

In this work, we systematically investigate the dibaryons with charm number $$C=1$$ C = 1 and strangeness number $$S=\pm $$ S = ± 1 from the interactions of a charmed baryon and a strange baryon $$\Lambda _c\Lambda $$ Λ c Λ , $$\Lambda _c\Sigma ^{(*)}$$ Λ c Σ ( ∗ ) , $$\Sigma _c^{(*)}\Lambda $$ Σ c ( ∗ ) Λ , and $$\Sigma ^{(*)}_c\Sigma ^{(*)}$$ Σ c ( ∗ ) Σ ( ∗ ) , and corresponding interactions of a charmed baryon and an antistrange baryon $$\Lambda _c{\bar{\Lambda }}$$ Λ c Λ ¯ , $$\Lambda _c{\bar{\Sigma }}^{(*)}$$ Λ c Σ ¯ ( ∗ ) , $$\Sigma ^{(*)}_c{\bar{\Lambda }}$$ Σ c ( ∗ ) Λ ¯ , and $$\Sigma ^{(*)}_c{\bar{\Sigma }}^{(*)}$$ Σ c ( ∗ ) Σ ¯ ( ∗ ) . With the help of the effective Lagrangians with SU(3), heavy quark, and chiral symmetries, the potentials of the interactions considered are constructed by light meson exchanges. To search for the possible molecules, the quasipotential Bethe–Salpeter equation with the interaction potential kernel is solved to find poles from scattering amplitude. The results suggest that attractions widely exist in charmed-strange system with $$C=1$$ C = 1 and $$S=-1$$ S = - 1 . The S-wave bound states can be produced from most of the channels. Few bound states are also produced from the charmed-antistrange interactions. Couple-channel effect are considered in the current work to discuss the couplings of the molecular states to the channels considered. More experimental research for these charmed-strange dibaryons are suggested.

“…Spintronics, which could take advantage of the spin degree of free electrons to realize the high-speed and low-energy-consumption information delivery and storage, are superior than conventional semiconductors and are desirable for applications in next-generation electronics. [14,15] In the past decades, the half-metallic materials, such as Heusler alloys, [16] manganese perovskites, [17] and transition metal oxides and dichalcogenides, [5,18] have been considered as suitable spintronic materials. In particular, the 2D half-metallic systems, such as GaSe, [19] buckled phosphorene, [20] SnO, [21,22] and InP 3 monolayers, [23] are much promising for applications in spintronics since they could possess fully spin-polarized carriers and ferromagnetisms as induced or tuned by carrier doping.…”

2D materials that possess multifunctional properties are of great interest for applications in semiconducting devices. Herein, a series of novel Janus XYP2 (X/Y = Si, Ge, Sn, and Pb; X ≠ Y) monolayers with good stability, electronic, mechanical, piezoelectric properties, as well as ferromagnetic properties are predicted based on density functional theory. They are all indirect‐bandgap semiconductors with bandgaps varying from 0.56 to 2.18 eV. The monolayers exhibit in‐plane and out‐of‐plane piezoelectricity with large piezoelectric coefficients, suggesting that they are promising piezoelectric materials for nanoelectromechanical systems. In SiGeP2, GeSnP2, and SnPbP2 monolayers, hole doping is found to be an effective approach in inducing or tuning different ferromagnetic states resulting from electronic instability as reflected by van Hove singularity of band structures in the 2D systems. The results suggest that Janus XYP2 monolayers can be promising 2D materials for applications in nanoelectronic, spintronic, and nanoelectromechanical devices.
