The BRFO system is antiferroelectric (AFE) with relatively large composition of rare earth, and it is predicted to be very promising for high-power energy storage. Additionally, a simple model is derived to describe the energy density and efficiency of a general AFE material, providing a framework to assess the effect on the storage properties of variations in doping, electric field magnitude and direction, epitaxial strain, temperature, etc., which can facilitate future search of antiferroelectric materials for energy storage.

The polarization switching mechanisms in intrinsic BFO is found to be homogeneous in the rhombohedral phase, for which the polarization is strongly coupled to oxygen octahedral tiltings. On the other hand, in the super-tetragonal phase the switching mechanism changes with increasing electric field, which can be explained by the field dependence of the switching barriers as well as the hierarchy of these barriers between different switching processes.

The inhomogeneous switching can lead to memristive behavior when it is used in ferroelectric tunnel junctions (FTJ). In this work we report spike-timing-dependent plasticity (STDP) from BFO-based FTJs. The STDP behavior relies on the change of resistance states (memristor), which originates from the intrinsic inhomogeneous polarization switching. Unsupervised learning of pattern recognition is further demonstrated.

In BRFO 1/1 superlattice (hybrid improper ferroelectric), the direction of the weak ferromagnetization can be controlled by the an electric field applied perpendicularly to the polarization. This is associated with two trilinear couplings connecting the polarization to the magnetic order, one being the trilinear coupling that leads to the hybrid improper ferroelelctricity, and the other is a Dzyaloshinskii-Moriya interaction.

In BRFO (R=Nd in this work) disordered solid solution, an applied electric field can trigger a paramagnetic-to-antiferromagnetic transition in BNFO solid solutions, which is due to the strong magnetoelectric coupling in the vicinity of a critical point (triple point) where large variation of both magnetic and electric orders can be expected.

With the fully-first-principles approach based on electron-phonon interactions, the abnormal sign of Seebeck coefficient in lithium is found to be due to stronger scattering of electrons than holes due to the significantly increasing density of states near the Fermi level. The electron-phonon interaction is found to be less relevant. Band engineering combined with this mechanism may open the door to new “ambipolar” thermoelectric materials, with a tunable sign for the thermopower even if either n- or p-type doping is impossible.

We combined first-principles calculations and high-pressure experiments to study pressure-induced phase transitions in Si3N4. Within the quasi-harmonic approximation, we predict that the α phase is always metastable relative to the β phase over a wide pressure-temperature range. Two competing phonon-softening mechanisms are predicted in the β-Si3N4. When the equilibrium β → γ transition is bypassed at room temperature (RT) due to kinetic reason, the β phase is predicted to undergo a first-order structural transformation to a denser P-6 phase above 39 GPa, confirmed by high-pressure x-ray diffraction experiment.

We demonstrate that the rhombohedral corundum phase and the orthorhombic Rh2O3(II) phase are structurally related by a diffusionless monoclinic common subgroup pathway, along which the intermediate structures have the space group P2/c symmetry. This transformation pathway is energetically favored because the majority of Al–O bonds are preserved during the transition. The calculated enthalpy barriers are consistent with the observed metastability of the corundum and Rh2O3(II) phases around room temperature.
