Positive effective Q(12) electrostrictive coefficient in perovskites

It is demonstrated that for classical perovskites, such as BaTiO3; SrTiO3, and PbTiO3, electrostrictive strain induced by an electric field may not obey traditionally considered "extension along the field and contraction perpendicular to it" behavior if th ...

Measurement of polarization-induced electric fields in GaN/AlInN quantum wells

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Etienne François Olivier Giraud, Marcus Gonschorek

GaN(Si)/AlInN multiple quantum wells were grown on GaN/Al2O3 (0001) templates by metalorganic vapor-phase epitaxy. Transmission electron microscopy observations showed well-defined GaN quantum wells and AlInN barrier layers. Electrostatic potential profile ...

Cold-Field Switching in PVDF-TrFE Ferroelectric Polymer Nanomesas

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Evgeny Mikheev

Polarization reversal in ferroelectric nanomesas of polyvinylidene fluoride with trifluoroethylene has been probed by ultrahigh vacuum piezoresponse force microscopy in a wide temperature range from 89 to 326 K. In dramatic contrast to the macroscopic data ...

Ferroelectric charged domain walls in an applied electric field

Nava Setter, Alexander Tagantsev, Maxim Gureev, Pavel Mokry

The interaction of electric field with charged domain walls in ferroelectrics is theoretically addressed. Ageneral expression for the force acting per unit area of a charged domain wall carrying free charge is derived. It is shown that, in proper ferroelec ...

Stark coefficients for highly excited rovibrational states of H2O

Thomas Rizzo, Oleg Boyarkine, Maxim Grechko, Oleg Aseev

Quantum beat spectroscopy is combined with triple-resonance vibrational overtone excitation to measure the Stark coefficients (SCs) of the water molecule for 28 rovibrational levels lying from 27 600 to 41 000 cm−1. These data provide a stringent test for ...

Estimation of Relative Position and Coordination of Mobile Underwater Robotic Platforms through Electric Sensing

Auke Ijspeert, Yannick Morel, Mathieu Porez

In the context of underwater robotics, positioning and coordination of mobile agents can prove a challenging problem. To address this issue, we propose the use of electric sensing, with a technique inspired by weakly electric fishes. In particular, the app ...

Measurement of effective piezoelectric coefficients of PZT thin films for energy harvesting application with interdigitated electrodes

Paul Muralt, Andrea Mazzalai, Nachiappan Chidambaram

Interdigitated electrode (IDE) systems with lead zirconate titanate (PZT) thin films play an increasingly important role for two reasons: first, such a configuration generates higher voltages than parallel plate capacitor-type electrode (PPE) structures, a ...

RF MEMS Shunt Capacitive Switches Using AlN Compared to Si3N4 Dielectric

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Elizabeth Buitrago Godinez

RF microelectromechanical systems (MEMS) capacitive switches for two different dielectrics, aluminum nitride (AlN) and silicon nitride (Si3N4), are presented. The switches have been characterized and compared in terms of DC and RF performance (5-40 GHz). S ...
