Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on
efficient light absorption, charge separation of electron–hole pair carriers or excitons, and …

We review the theoretical, computational, and synthetic literature on hybrid improper
ferroelectricity in layered perovskite oxides. Different ferroelectric mechanisms are described …

Cross phenomena, representing responses of a system to external stimuli, are ubiquitous
from quantum to macro scales. The Onsager theorem is often used to describe them, stating …

The discovery of ferroelectricity in aluminum scandium nitride (Al1–x Sc x N) opens
technological perspectives for harsh environments and space-related memory applications …

Fluorite-structure ferroelectrics—in particular the orthorhombic phase of HfO 2—are of
paramount interest to academia and industry because they show unprecedented scalability …

Solvation plays a pivotal role in chemistry and biology. A solid-state analogy of solvation is
polaron formation, but the magnitude of Coulomb screening is typically an order of …

Hysteretic switching with a sub-kT/q steep slope (13 mV/decade at room temperature) is
experimentally demonstrated in MOSFETs with PbZr 0.52 Ti 0.48 O 3 as a ferroelectric (FE) …

Ferroelectric transistors (FeFETs) based on doped hafnium oxide (HfO2) have received
much attention due to their technological potential in terms of scalability, high-speed, and …

Ferroelectric materials have technological applications in information storage and electronic
devices. The ferroelectric polar phase can be controlled with external fields, chemical …

We address the sliding thermodynamics of van der Waals-bonded bilayers by continuum
electromechanics. We attribute the robustness of the ferroelectricity recently observed in h …
