Article 12 – Flexocoupling-induced phonons and ferrons in van der Waals ferroelectrics
Abstract: The contribution of flexoelectric coupling to the long-range order parameter fluctuations in ferroics can be critically important to the ferron dispersion and related polar, pyroelectric, and electrocaloric (EC) properties. Here, we calculate analytically the dispersion relations of soft optic and acoustic flexocoupling-induced phonons and ferrons by incorporating the flexoelectric coupling, damping, and higher elastic […]
Article 11 – Quantitative 3D Optical Birefringence in Peptide Bioelectrets
Abstract: Peptide nanotubes (PNTs) are bioelectrets that exhibit piezoelectricity, pyroelectricity, ferroelectricity, and birefringence. Birefringence is an optical property that can be used to determine the degree of order, orientation, size, and shape of PNTs. In this work, a custom-built optical apparatus is used to quantitatively measure birefringence in three dimensions of PNTs under varying electric […]

Article 10 – Electromechanical coupling in polaronic ceria
Abstract: Oxygen-defective metal oxides like cerium oxides exhibit giant electrostriction and field-induced piezoelectricity due to a dynamic electrosteric interplay between oxygen defects, V··O, and the fluorite lattice. While such mechanisms are generally attributed to oxygen vacancies, recent results also highlight that trapped cationic defects, Ce′Ce, i.e. small polarons, can contribute to the electromechanical properties of […]

Article 9 – Strain-Polarization Coupling in the Low-Dimensional Van der Waals Ferrielectrics
Abstract: Using the Landau-Ginzburg-Devonshire phenomenological approach we explore the strain-polarization coupling in the low-dimensional van der Waals ferrielectrics. We evolve the analytical model of the piezoelectric susceptibility of the material in response to the periodic strain modulation, such as caused by a surface acoustic wave. Numerical calculations are performed for recently discovered and poorly studied […]
Article 8 – Coexistence and interplay of two ferroelectric mechanisms in Zn1-xMgxO
Abstract: Ferroelectric materials promise exceptional attributes including low power dissipation, fast operational speeds, enhanced endurance, and superior retention to revolutionize information technology. However, the practical application of ferroelectric-semiconductor memory devices has been significantly challenged by the incompatibility of traditional perovskite oxide ferroelectrics with metal-oxide-semiconductor technology. Recent discoveries of ferroelectricity in binary oxides such as Zn1-xMgxO […]
