Abstract In the realm of ferroelectric memories, HfO 2 -based ferroelectrics stand out because their exceptional CMOS compatibility and scalability. Nevertheless, switchable polarization switching speed are not on par with those perovskite ferroelectrics. It is widely acknowledged that defects play a crucial role in stabilizing metastable polar phase . Simultaneously, also pin domain walls impede process, ultimately rendering sluggish Herein, we present an effective strategy involving...
Abstract Topological domain structures have drawn great attention as they potential applications in future electronic devices. As an important concept linking the quantum and classical magnetism, a magnetic Bloch point, predicted 1960s but not observed directly so far, is singular point around which magnetization vectors orient to nearly all directions. Here we show polar points tensile-strained ultrathin ferroelectric PbTiO 3 films, are alternatively visualized by phase-field simulations...
Using the large-scale atomic/molecular massively parallel simulator, fraction of Cu-centered ⟨0,0,12,0⟩ full icosahedra (fico) is obtained from a statistical analysis over broad compositional range with high resolution in Cu–Zr binary system. Weak but significant peaks are observed at certain compositions which coincide good glass formers. This correlation implies that change fico fundamental structural factor determining ease formation. In this regard, can be an indicator glass-forming...
A combined experimental and computational study was carried out to investigate magnetic properties of NiO nanostructures. Remarkable size-dependent magnetism discovered. Uniform amorphous showed a dominated antiferromagnetic interaction an ordering temperature $3.5\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. clusters (up $1\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$) tend be ferromagnetic with $35\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, accompanied by high magnetization...
Antiferroelectric materials have shown great potential in electronic devices benefiting from the reversible phase transition between ferroelectric and antiferroelectric phases. Understanding dipole arrangements clear pathways is crucial for design of materials-based energy storage conversion devices. However, specific details remain largely unclear even controversial to date. Here, we grown a series PbZrO
The empirical pseudopotential method within the virtual crystal approximation is used to calculate band structure of Mg1-xZnxSySe1-y, which has recently been proved be a potential semiconductor material for optoelectronic device applications in blue spectral region. It shown that MgZnSSe can direct or an indirect depending on alloy composition. Electron and hole effective masses are calculated different compositions. Polynomial approximations obtained both energy gap mass as functions...
Single-crystalline CaMn3O6 nanoribbons have been synthesized by a molten-salt method. To explore the origin of magnetism nanosized antiferromagnetic (AFM) manganites, comparative study has conducted for (CMO-1) and post-growth vacuum annealed (CMO-2) nanoribbons. A lattice expansion resulting from oxygen release during annealing is observed. Correspondingly, AFM ordering in CMO-2 further suppressed, ferromagnetism spin-glass (SG)-like behavior are significantly enhanced, which presumed...
