Abstract
Based on density functional theory (DFT), structural properties, elastic stability, electronic stability, magneto-optic Kerr effect (MOKE) and band offsets were determined by applying GGA and HSE06 approximations, with van der Waals (vdW) switch of MnO2/AlN and MnO2/SiC heterostructures (HSs) have been investigated. The result of energy calculations and elastic parameters show the stability of these two HSs. MnO2/AlN vdWHSs and MnO2/SiC vdWHSs have an indirect band gap characterized by type-I band alignment, which can specifically locate photogenerated charge carriers. Also, the investigation of magneto-optical parameters of these vdWHSs shows the change of and angles up to about 0.9° for MnO2/AlN vdWHSs. The ferromagnetic property of MnO2 layer has broken the time-reversal symmetry and enabled MOKE in these two vdWHS. More interestingly, the study of the band structure diagram showed that these two vdWHSs are semi-metals in the GGA approximation, and changing the spin direction from up to down along with applying the HSE approximation will lead to topological behavior in them.
期刊介绍:
Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged.
A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions.
The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
