Description of electric field-dependent dielectric permittivity in PMN ceramics
(2019-01-01)
The temperature dependences of the linear and nonlinear components of the dielectric permittivity of PMN ceramics were determined as a function of bias electric fields. The influence of the applied bias electrical field, ...
Electric field and energy of a point electric charge between confocal hyperboloidal electrodes
(Revista Mexicana de Física, 2009)
Electric field and electric potential due to a finite cylindrical surface charge distribution considering a linearly variable surface charge density
(IOS Press, 2016-08)
This paper proposes a fast and accurate method for determining the electric potential and the radial and axial components of electric field intensity produced by a finite cylindrical surface charge distribution. The surface ...
Electrical properties of the SnO2-based varistor
(1998-12-01)
The non-linear electrical properties of CoO-doped and Nb205-doped SnO2 ceramics were characterized. X-ray diffraction and scanning electron microscopy indicated that the system is single phase. The electrical conduction ...

Simulation of needle-type corona electrodes by the finite element method
(2007-12-01)
This paper describes a software tool, called LEVSOFT, suitable for the electric field simulations of corona electrodes by the Finite Element Method (FEM). Special attention was paid to the user friendly construction of ...
Strain- and electric field-induced band gap modulation in nitride nanomembranes
(2013-05-15)
The hexagonal nanomembranes of the group III-nitrides are a subject of interest due to their novel technological applications. In this paper, we investigate the strain- and electric field-induced modulation of their band ...
Effect of Cr2O3 in the varistor behaviour of TiO2

Consistency restrictions on maximal electric-field strength in quantum field theory
(AMER PHYSICAL SOC, 2008)
Quantum field theory with an external background can be considered as a consistent model only if backreaction is relatively small with respect to the background. To find the corresponding consistency restrictions on an ...
Electric-field effects on the closed orbits of the diamagnetic Kepler problem
(2016-02-05)
The nonrelativistic closed orbits of an electron interacting with a unit positive charge in the presence of homogeneous magnetic and electric fields are investigated. A simplified theoretical model is proposed utilizing ...
