NaN02 is a famous ferroelectric material with spontaneous polarization (Ps) along the crystallographic b-axis, which undergoes an order-disorder transition at Tc = 437 K [1 3]. The Ps, arising from the ordering of N 0 2 and the accompanying shift of Na, is sensitive to the environment. Information on the local structure in NaN02 has been obtained by employing N NQR [4 5]. A change of the local ...

Major issues of NBI power supplies are a high-speed switching, regulation and transmission of dc ultra high voltage, and suppression of surge energy input to the beam source at breakdown. A GTO(gate turn off thyristor) inverter type power supply where the control is performed at low voltage ac side was designed for the ITER NB. Based on the remarkable progress of a high power IEGT (injection en...

This work reports on theoretical and experimental study of zero-order as well as high-order symmetric and asymmetric modes of Lamb-wave resonators and delay line structures realized in single-crystalline GaN thin films. We investigate the phase velocity, dispersion characteristics, electromechanical coupling (kt), motional impedance (Rm) and Quality factor (Q) of different Lamb-wave modes (e.g....

The anterior lateral line nerve of the thornback ray consists of fibers that innervate head electroreceptive ampullary organs and mechanoreceptive neuromasts. As the anterior lateral line nerve enters the medulla it divides into dorsal and ventral roots. Single unit responses of dorsal root fibers to electric field and mechanical stimuli indicate that the dorsal root consists only of ampullary ...

Forecasting the geomagnetic e ects to technological systems on the ground requires rapid calculations of the electric and magnetic elds produced by the auroral electrojet. The electrojet is often modelled as a line current at a height of 100 km, but in reality it has a nite width and is typically spread over 5◦ or 6◦ of latitude. We show that the width of the electrojet can easily be included i...

In this work we theoretically and experimentally analyze the resonant behavior of individual 3 × 3 gold particle oligomers illuminated under normal and oblique incidence. While this structure hosts both dipolar and quadrupolar electric and magnetic delocalized modes, only dipolar electric and quadrupolar magnetic modes remain at normal incidence. These modes couple into a strongly asymmetric sp...

In the generation of photoemitted electron bunches for the use in accelerators, metals are limited by their low QE. Previous work [P. Musumeci et al., Phys. Rev. Lett. 110(2013)] has shown that charge yield from infrared light is increased by a factor of 120 by etching nanopatterns into the cathode. However, utility of the electron bunch is also based on its thermal emittance, or angular spread...

A simulation of electric current pulses formed by a packet of gamma-quanta moving through an absorptive medium is presented. The electromagnetic fields of the current pulse moving along the straight line with super light velocity are obtained.

We control the electrostatic environment of a single InAsP quantum dot in an InP nanowire with two contacts and two lateral gates positioned to an individual nanowire. We empty the quantum dot of excess charges and apply an electric field across its radial dimension. A large tuning range for the biexciton binding energy of 3 meV is obtained in a lateral electric field. At finite lateral electri...
