Controlled stripes of ultrafine ferroelectric domains

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Tomas Sluka, Petr Yudin, Silviu Cosmin Sandu, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov, Xiankui Wei

In the pursuit of ferroic-based (nano) electronics, it is essential to minutely control domain patterns and domain switching. The ability to control domain width, orientation and position is a prerequisite for circuitry based on fine domains. Here, we deve ...

Free-electron gas at charged domain walls in insulating BaTiO3

Nava Setter, Alexander Tagantsev, Tomas Sluka, Petr Bednyakov

Hetero interfaces between metal-oxides display pronounced phenomena such as semiconductor-metal transitions, magnetoresistance, the quantum hall effect and superconductivity. Similar effects at compositionally homogeneous interfaces including ferroic domai ...

Enhanced electromechanical response of ferroelectrics due to charged domain walls

Nava Setter, Dragan Damjanovic, Alexander Tagantsev, Tomas Sluka, Maxim Gureev

While commonly used piezoelectric materials contain lead, non-hazardous, high-performance piezoelectrics are yet to be discovered. Charged domain walls in ferroelectrics are considered inactive with regards to the piezoelectric response and, therefore, are ...

Adaptive Vibration Suppression System: An Iterative Control Law for a Piezoelectric Actuator Shunted by a Negative Capacitor

Tomas Sluka, Pavel Mokry

An adaptive system for the suppression of vibration transmission using a single piezoelectric actuator shunted by a negative capacitance circuit is presented. It is known that by using a negative-capacitance shunt, the spring constant of a piezoelectric ac ...

A theory of sound transmission through a clamped curved piezoelectric membrane connected to a negative capacitor

Hervé Lissek, Tomas Sluka, Pavel Mokry

An analytical calculation of the acoustic transmission loss of sound propagating through a thin cylindrically curved piezoelectric membrane, which is rigidly clamped at its straight ends, is presented. The membrane is placed inside an acoustic tube and con ...
