Proximity Ferroelectricity in Compositionally Graded Structures

open access: yesAdvanced 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 ...

Materials Design Principles for Large Memory Windows: Coercive Voltage Engineering in Ferroelectric– Dielectric Heterostructures

open access: yesAdvanced 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 ...

Performance Enhancement in Hafnium Oxide Through Homogeneous and Heterogeneous co‐Doping Strategies

open access: yesAdvanced Electronic Materials, EarlyView.
This article presents a comprehensive co‐doping toolkit to optimize the performance and reliability of fluorite‐structure ferroelectrics like hafnium oxide. By employing homogeneous and heterogeneous co‐doping strategies, precise control over crystallization behavior, polarization hysteresis, and oxygen vacancy distribution is achieved.

Concealable and Field‐Free Physical Unclonable Function Based on Voltage‐Controlled Magnetic Tunnel Junctions

open access: yesAdvanced Electronic Materials, EarlyView.
A concealable physical unclonable function (PUF) based on an array of 384 nanoscale voltage‐controlled magnetic tunnel junctions is demonstrated. The PUF operates without any external magnetic field. It uses a combination of deterministic and stochastic switching mechanisms, based on the spin transfer torque and voltage‐controlled magnetic anisotropy ...

Non‐volatile Sliding Ferroelectric Memory Effect in Ultrathin γ‐InSe

open access: yesAdvanced Electronic Materials, EarlyView.
Room‐temperature sliding ferroelectricity in γ‐InSe enables a two‐dimensional FeFET with a 6.8 V memory window, above 104 conductance modulation, longer than 10‐years retention and above 103 cycles fatigue resistance. An ultrathin (4.8 nm) γ‐InSe ferroelectric tunnel junction exhibits reversible high/low resistance switching with TER of 105 at room ...

Toward Capacitive In‐Memory‐Computing: A Device to Systems Level Perspective on the Future of Artificial Intelligence Hardware

open access: yesAdvanced Intelligent Discovery, EarlyView.
Capacitive, charge‐domain compute‐in‐memory (CIM) stores weights as capacitance,eliminating DC sneak paths and IR‐drop, yielding near‐zero standbypower. In this perspective, we present a device to systems level performance analysis of most promising architectures and predict apathway for upscaling capacitive CIM for sustainable edge computing ...
