CrSBr is a recently discovered two-dimensional anti-ferromagnet. It has attracted much attention due to its superior properties for potential optoelectronic and spintronic applications. However, its complex refractive index with layer dependence has not been systematically studied yet. In this work, we studied the room-temperature complex refractive indices of thin CrSBr flakes of different thicknesses in the visible light range. Using micro-reflectance spectroscopy, we measured the optical contrast of thin CrSBr flakes with respect to different substrates. The complex refractive index was ext

CrSBr is a stable two-dimensional (2D) van der Waals (vdW) magnet with intralayer ferromagnetic and interlayer antiferromagnetic couplings. Here, we propose to use CrSBr as the barrier in spin-filter (sf) MTJ and establish the devices based on graphene/CrSBr/graphene structures. Employing density functional theory (DFT) combined with the nonequilibrium Green’s function approach, we investigated the transmission details, and the results show TMR values above 330%, 2 × 107% and 105% with two-, four- and six-layer CrSBr at zero bias, respectively.

Abstract: Monolayers of semiconducting transition metal dichalcogenides (TMDCs) are known for their unique excitonic photoluminescence (PL), which can be tuned by interfacing them with other materials. However, integrating TMDCs into van der Waals heterostructures often results in a significant quenching of the PL because of an increased rate of nonradiative recombination processes.

AbstractMagnetism in two-dimensional materials reveals phenomena distinct from bulk magnetic crystals, with sensitivity to charge doping and electric fields in monolayer and bilayer van der Waals magnet CrI3. Within the class of layered magnets, semiconducting CrSBr stands out by featuring stability under ambient conditions, correlating excitons with magnetic order and thus providing strong magnon-exciton coupling, and exhibiting peculiar magneto-optics of exciton-polaritons. Here, we demonstrate that both exciton and magnetic transitions in bilayer and trilayer CrSBr are sensitive to voltage-

AbstractTwo-dimensional van der Waals Janus materials and their heterostructures offer fertile platforms for designing fascinating functionalities. Here, by means of systematic first-principles studies on van der Waals Janus monolayer Cr-based dichalcogenide halides CrYX (Y = S, Se, Te; X = Cl, Br, I), we find that CrSX (X = Cl, Br, I) are the very desirable high TC ferromagnetic semiconductors with an out-of-plane magnetization.

Abstract Photodetectors equipped with multi-parameter control hold the potential to deliver exceptional performance in a wide range of scenarios, paving the way for developing novel spin-opto-electronic devices. Nevertheless, the integration of such capabilities within a single device is challenging due to the necessity of harmonizing multiple materials with varying degrees of freedom. In this study, we introduce the van der Waals magnet CrSBr, featuring inherent anisotropy and distinctive spin-electronic coupling, to this realm.

Abstract Two-dimensional (2D) van der Waals (vdW) magnetic materials have demonstrated great potential for new-generation high-performance and versatile spintronic devices. Among them, magnetic tunnel junctions (MTJs) based on A-type antiferromagnets, such as CrI3, possess record-high tunnelling magnetoresistance (TMR) because of the spin filter effect of each insulating unit ferromagnetic layer. However, the relatively low working temperature and the instability of the chromium halides hinder the applications of this system. Using a different technical scheme, we fabricated the MTJs based on

Scanning transmission electron microscopy is a powerful tool for defect identification in atomically thin materials, and extending it to multilayer and beam-sensitive materials would accelerate their exploration. Here, we establish a comprehensive defect library in a bilayer of the magnetic quasi-1D semiconductor CrSBr by combining atomic-resolution imaging, deep learning, and calculations.

We report temperature-dependent reflectivity spectra of the layered van der Waals magnet CrSBr in the far-infrared region. Polarization-dependent measurements resolve the vibrational modes along the E∥a and b axes and reveal clear structural anisotropy. While the a-axis phonons notably harden on cooling, the b-axis phonon frequencies are almost temperature independent. A phonon splitting due to the antiferromagnetic phase transition is observed for the 180 cm−1 a-axis vibrational mode, accompanied by a phonon softening below TN. Furthermore, an additional mode with strong magnetic characterist

Here we present a proof-of-concept device demonstrating the feasibility to control the light polarization using the properties of the magnetic 2D materials. The studied structure consists of a diluted magnetic semiconductor quantum well and a thin layer of CrSBr. We show that by application of the external field we can switch the sign of the polarization of the emitted light. The theoretical modeling confirms that such a switching is a direct consequence of a colossal shift of the exciton lines observed in the high energy range of the CrSBr spectra.

van der Waals magnetic materials are an ideal platform to study low-dimensional magnetism. Opposed to other members of this family, the magnetic semiconductor CrSBr is highly resistant to degradation in air, which, in addition to its exceptional optical, electronic, and magnetic properties, is the reason the compound is receiving considerable attention at the moment. For many years, its magnetic phase diagram seemed to be well-understood. Recently, however, several groups observed a magnetic transition in magnetometry measurements at temperatures of around 40 K that is not expected from theore

Abstract Two-dimensional (2D) materials, particularly those with intrinsic magnetism, hold promise for next-generation spintronic devices due to their unique electronic and magnetic properties. This study investigates the impact of in-plane uniaxial and biaxial strain on the properties of monolayer CrSBr using density functional theory (DFT) and Monte Carlo (MC) simulations. We demonstrate that strain engineering can effectively modulate the electronic band structure and Curie temperature (Tc) of the CrSBr monolayer. Under uniaxial strains, transitions from indirect to direct bandgaps are obse
