Recipes for improper ferroelectricity in molecular perovskites

Nature Communications, 2018
In layered inorganic materials lattice distortions can couple to break inversion symmetry and drive improper ferroelectricity, but in perovskites, symmetry prohibits such an effect.

Hydrogen in Ferroelectrics [PDF]

, 2011
It is well known that the ferroelectric random access memories (FRAM) as one of the most important applications of ferroelectric thin film have attracted much attention. However, the introduction of hydrogen into ferroelectric materials may cause severe degradations in dielectric properties, ferroelectric properties, optical properties and mechanical ...

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
