Lately, because of the toxicity of lead and lead compounds, the interest in ferroelectric
materials without lead has grown considerably.
material has electrical polarization that is reversed by application of an electric field.
Devices & Piezoelectric Actuators: Research Misconceptions and Rectifications
But Kakekhani and Sohrab Ismail-Beigi, also at Yale, identified a way to use ferroelectric
oxides to catalytically separate hydrogen from oxygen more effectively.
Their potential to be used as high permittivity dielectrics [1-6], organic ferroelectric
memory devices [7, 8], electrostrictive actuators [9-12], and high energy density capacitors [13-20] has been widely studied over the last few decades.
Monte Carlo Simulation of Ferroelectric
Behavior in PZT Films by Using a Stress Dependent DIFFOUR Hamiltonian
Yokohama, Japan, Apr 8, 2014 - (JCN Newswire) - Employees of Fujitsu Semiconductor Limited have received "Prize for Science and Technology (Development Category)" of "Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology", on their work for the "Development of the Volume Production Technology for High Density Ferroelectric
Random Access Memory".
Ferroelectricity is an electrical phenomenon of ferroelectric
materials may exhibit a spontaneous polarization which the direction of the polarization can be switched by the application of an external electric field.
The new molecule is a ferroelectric
, meaning it is positively charged on one side and negatively charged on the other, where the direction can be flipped by applying an electrical field.
Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (BNL) has provided the first atomic-scale insights into the ferroelectric
properties of nanocrystals using electron beams as the interfering medium.
Among the topics are the thermodynamic approach, deposition and patterning technologies, radio frequency characterization, integrated capacitors, and ferroelectric
Information can be stored in a ferroelectric
material in the form of an electric dipole moment in a class of devices known as "ferroelectric
-field-effect-transistors" or more commonly as FFETs.
