Two dimensional transition metal trihalides have drawn attention over the years due to their intrinsic ferromagnetism and associated large anisotropy at nanoscale. The interactions involved in these layered structures are of van der Waals types which are important for exfoliation to different thin samples. This enables one to compare the journey of...

Bi4Br4 is a quasi-one-dimensional van der Waals topological insulator with novel electronic properties. Several efforts have been devoted to the understanding of its bulk form, yet it remains a challenge to explore the transport properties in low-dimensional structures due to the difficulty of device fabrication. Here we report for the first time a...

Reduced dielectric screening in two-dimensional materials enables bound excitons, which modifies their optical absorption and optoelectronic response. Here, we demonstrate the existence of excitons in the bandgap of the monolayer family of the newly discovered synthetic MoSi2Z4 (Z=N, P, and As) series of materials. All three monolayers support seve...

We propose a systematic method to construct crystal-based molecular structures often needed as input for computational chemistry studies. These structures include crystal ‘slabs’ with periodic boundary conditions (PBCs) and non-periodic solids such as Wulff structures. We also introduce a method to build crystal slabs with orthogonal PBC vectors. T...

The electronic structure and optical response of ZnSe are studied in this work. The studies are carried out using first-principles full-potential linearized augmented plane wave method. After settling the crystal structure, the electronic band structure of the ground state of ZnSe is calculated. Linear response theory is applied to study optical re...

The paper investigates vortex-like structures observed in ferromagnetic films with strong uniaxial easy-plane anisotropy in the presence of topological features in them. Two approaches to the creation of such features are considered, namely, perforation of the sample and the inclusion of artificial defects in it, and a theorem on their equivalence ...

The disorder in any system affects their physical behavior. In this scenario, we report the possibility of disorder in A2BB′O6 oxides and their effect on different magnetic properties. These systems show anti-site disorder by interchanging B and B′ elements from their ordered position and giving rise to an anti-phase boundary. The presence of disor...

We discretize the Schrödinger equation in the approximation of the effective mass for the two-dimensional electron gas of GaAs, without magnetic field and on the other hand, with magnetic field. This discretization leads naturally to Tight Binding (TB) Hamiltonians in the approximation of the effective mass. An analysis of this discretization allow...

In this study, we evaluated the dependence of magnetization of three-dimensional Dirac electrons in the quantum limit on the magnetic field and temperature. The magnetization was calculated by differentiating the free energy with respect to the magnetic field. The field and temperature dependence of the chemical potential were entirely considered u...

In the breakthrough progress made in the latest experiment Hou et al (2022 Nature 606 507), 2D C60 polymer was exfoliated from the quasi-hexagonal bulk crystals. Bulk C60 polymer with quasi-tetragonal phase was found to easily form 1D fullerene structure with C60 molecules connected by C=C. Inspired by the experiment, we investigate the strain beha...
