Ferroelectricity-Driven Phonon Berry Curvature and Nonlinear Phonon Hall Transports
Berry curvature (BC) governs topological phases of matter and generates anomalous transport. When a magnetic field is applied, phonons can acquire BC indirectly through spin–lattice coupling, leading to a linear phonon Hall effect.

The Rise of Ferroelectricity at Nanoscale: Nanoelectronics is rediscovering the ferroelectricity
IEEE Nanotechnology Magazine, 2021 We present a comprehensive review of the emerging nanoscale ferroelectric materials used in novel nanoelectronics devices. First, we outline specific physical and electronic properties of ferroelectric materials, then we focus on two main classes of ferroelectrics based on hafnium oxide (HfO2) and 2D materials.

Ferroelectricity enhancement in ferroelectric nanotubes [PDF]
Phase Transitions, 2007 In this paper we study the size effects of the ferroelectric nanotube phase diagrams and polar properties allowing for effective surface tension and depolarization field influence. The approximate analytical expression for the paraelectric-ferroelectric transition temperature dependence on the radii of nanotube, polarization gradient coefficient ...
