Silver bismuth iodide (Ag–Bi–I) is considered to be a potential photovoltaic material as an eco-friendly semiconductor with suitable band gap and high stability. However, the reported highest PCE still far below ideal value, quality of AgxBiyIx+3y film deserves further improved. Herein, we introduce facile strategy control crystallization AgBiI4 by adding Lewis base additives thiourea (TU) precursor solution. The result indicates that coordination between TU solution improves...
With the discovery of two-dimensional (2D) ferroelectricity and ferromagnetism in van der Waals (vdW) materials, there has been significant interest 2D multiferroics. Herein, we report occurrence weak magnetoelectricity vdW antiferromagnet MnPSe3 single crystals. Our results demonstrate that undergoes an antiferromagnetic transition at Néel temperature TN = 70 K with along [1–10] direction. Detailed magnetoelectric (ME) data show exhibits a linear ME tensor αij nine nonzero components....
It is known that the utilization of exchange bias (EB) effect for data storage underscores its importance. However, achieving a giant EB with small cooling field (HCF) in single-phase materials remains challenge. This study unveils value within material, Fe2−xGaxTeO6 (FGTO), originating from anchoring spin-glass phase by antiferromagnetic order. Manipulating relative strengths and order parameters Ga3+-substitution Fe3+ ions Fe2TeO6 lattice governs magnitude effect. found FGTO single...
Abstract The moiré-pattern with slightly interlayer-twisted bilayer two-dimensional (2D) materials has recently been receiving substantial attention. One of the major characters for these intriguing structures is appearance low-energy ultra-flat bands and thus a package new physics associated strong electron correlation emerges. However, such may become vague unless twist-angle θ sufficiently small as ∼ 1°, making practical applications control-flexibility hard to handle. In this work, we...
The AgBiI 4 films were synthesized with different antisolvents. It indicates that an antisolvent suitable polarity, low boiling point, and high miscibility host solvent is preferred in improving the film quality photovoltaic performance of solar cells.
Antiferromagnetic spintronics has been receiving attention recently, while spin-texture dependent magnetoresistance (MR) represents one of the main mechanisms for magnetic data storage. In particular, sufficiently large MR with high operating temperatures would be highly required advanced spintronic applications. this work, we experimentally investigate effect well-known antiferromagnet α-Fe2O3 (hematite) in a single crystal form, which Morin transition temperature as Tm ∼ 260 K. It is...
A ferroelectric thin film epitaxially deposited on a substrate is usually subjected to the mixed mechanical boundary conditions that can neither be treated as purely fixed-strain boundaries nor fixed-stress ones, thus causing inconsistency or inaccuracy for choice of Helmholtz Gibbs thermodynamic potential. It would interest clarify this and set up some rules such choice. In work, we discuss various roadmaps construct two types modified potentials under epitaxial conditions. The equivalence...
