Heterojunctions have received much interest as a way to improve semiconductors' electrical and optical properties. The impact of the interface on properties g-C3N4/SnS2 was explored using first-principles calculations in this study. results show that, at hetero-interface, conventional type-II band forms, resulting lower gap than that g-C3N4 SnS2 monolayers. When there is no high barrier height, averaged microscopic macroscopic potentials can be used accomplish efficient carrier...

According to a first-principles study of the transport properties two thiolated anthracene-9,10-diono molecules sandwiching ethyl, new method induce molecular low bias negative differential resistance with multi-peaks for strong n- or p-type is proposed. The molecule shows n-type characteristics when in contact Au and Ag electrodes via thiolate. multiple effect originated from molecule–electrode couple different between electrodes. Our investigations may promise potential applications...
The lateral shifts (i.e., the spatial GH shifts) of reflected wave from a uniaxial anisotropic chiral metamaterial slab are predicted based on stationary-phase method. two cases investigated in detail. It is found that negative can be realized for both as group refraction left circularly polarized (LCP) negative. perpendicular component (Δsp) similar cases, which enhanced at close-to-grazing incidence. However, parallel (Δpp) near Brewster angle. For case (I), by introducing different...
Charge dipole moment and spin rarely coexist in single-phase bulk materials except some multiferroics. Despite the progress past decade, for most multiferroics their magnetoelectric performance remains poor due to intrinsic exclusion between charge moment. As an alternative approach, oxide heterostructures may evade limits provide more attractive potential realize functions. Here we perform a first-principles study on LaAlO$_3$/PbTiO$_3$ superlattices. Although neither of components is...
Based on density functional theory, we elucidate the origin of ferroelectricity multiferroic CuFeO2 with collinear and noncollinear magnetic structure calculations. By comparing lattice geometry electronic structures different orderings, confirm that up-up-down-down spin arrangement plays an important role in formation band gap, decrease total energy, increase moment. However, system undergoes a large distortion due to helical-spin ordering. In particular, strong hybridizations Fe 3d O 2p...
In the framework of Landau–Devonshire thermodynamic theory, which is used in conventional ferroelectrics, we investigate ferroelectric properties 1–3 type multiferroic BaTiO3–CoFe2O4 nanocomposite films. The films are epitaxial both plane and out with self-assembled hexagonal arrays CoFe2O4 nanopillars embedded a BaTiO3 matrix present tantalizing possibility heteroepitaxy three dimensions. It shown that thin such as polarization, piezoelectric coefficient, dielectric susceptibility, etc.,...
