Diffusion–Model–Driven Discovery of Ferroelectrics for Photocurrent Applications
Advanced Science, EarlyView.We developed a diffusion model–based generative AI and high‐throughput screening framework that accelerates the discovery of photovoltaic ferroelectrics. By coupling AI driven crystal generation with machine learning and DFT screening, we identified Ca3P2 and LiCdP as new ferroelectric materials exhibiting strong polarization, feasible switching ...

Fundamental Energy Requirement of Reversible Quantum Operations
Physical Review X, 2021 Landauer’s principle asserts that any computation has an unavoidable energy cost that grows proportionally to its degree of logical irreversibility. But even a logically reversible operation, when run on a physical processor that operates on different ...

Entropy production and fluctuations in a Maxwell's refrigerator with squeezing
, 2018 Clarifying the impact of quantumness in the operation and properties of thermal machines represents a major challenge. Here we envisage a toy model acting either as an information-driven fridge or as heat-powered information eraser in which coherences ...

Influence of Bottom Electrodes on the Ferroelectric Stability of AlScN Film at High Temperatures
Advanced Electronic Materials, EarlyView.The thermal stability of AlScN depends on the bottom electrode. When the bottom electrode possesses compressive stress, tensile strain develops in the AlScN upon thermal annealing, reducing the switching barrier. When the bottom electrode forms a coherent interface with AlScN, significant tensile strain and defects are generated in the AlScN layer ...

Proximity Ferroelectricity in Compositionally Graded Structures
Advanced Electronic Materials, EarlyView.We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...

Advanced Electronic Materials, EarlyView.Coercive voltage enhancement in hafnia‐based ferroelectric–dielectric heterostructures is shown to originate from leakage‐governed voltage division between the ferroelectric and dielectric layers. Through experiments, circuit modeling, and defect‐based simulations, a universal framework is established to engineer large memory windows without altering ...

Propagation of signals in the chains of bi-stable elements
AIP Advances, 2015 This article is devoted to treating the behavior of systems composed of an ensemble of bi-stable cells which are capable to write and store information and are connected with similar cells placed along one dimensional direction so as information can ...
