Ferroelectric Field‐Effect‐Transistor Integrated with Ferroelectrics Heterostructure

Advanced Science, 2022
AbstractTo address the demands of emerging data‐centric computing applications, ferroelectric field‐effect transistors (Fe‐FETs) are considered the forefront of semiconductor electronics owing to their energy and area efficiency and merged logic–memory functionalities. Herein, the fabrication and application of an Fe‐FET, which is integrated with a van

Compositing Effect Leads to Extraordinary Performance in GeSe‐Based Thermoelectrics

Advanced Functional Materials, EarlyView.
Rhombohedral GeSe is rationally designed with (GeSe)0.9(AgBiTe2)0.1‐1.5 mol.% SnSe, achieving a peak ZT of 1.31 at 623 K. Forming a composite with SnSe establishes interfaces with strong phonon scattering and weak electron scattering. Multiscale defects lead to an ultra‐low lattice thermal conductivity (0.26 W m−1 K−1), approaching the amorphous limit.

Ferroelectric negative capacitance [PDF]

Nature Reviews Materials, 2019
The capacitor is a key element of electronic devices and is characterized by positive capacitance. However, a negative capacitance (NC) behaviour may occur in certain cases and implies a local voltage drop opposed to the overall applied bias. Therefore, a local NC response results in voltage enhancement across the rest of the circuit. Within a suitably

Superparaelectric phase in the ensemble of non-interacting ferroelectric nanoparticles

, 2008
For the first time we predict the conditions of superparaelectric phase appearance in the ensemble of non-interacting spherical ferroelectric nanoparticles. The superparaelectricity in nanoparticle was defined by analogy with superparamagnetism, obtained

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

Advanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Optical Control of Ferroelectric Imprint in BiFeO3

Advanced Functional Materials, EarlyView.
Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...
