The surface electric field E and Maxwell current density JM have been measured simultaneously under and near small Florida thunderstorms. These records show that the amplitude of JM is of the order of 1 nA/m2 or less in the absence of precipitation and that there are regular time variations ...
For a well conditioned sample the peak current is strongly dependent on the charging electric field and on the mean trapping depth of the injected charge... ER Neagu,JN Marat-Mendes - 《Materials Science Forum》 被引量: 0发表: 2006年 The Local Electric Field in Photorefractive and Other Sem...
My problem statement is like, one meter length semiconductor wire (Ge) and radius is 0.3mm. if i am applying 25V DC across the wire.. is it possible that comsol solve that how much current is flowing and electric field is there in the wire.. if it is possible than please some one ...
In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti

generated from high-voltage direct-current transmission lines can induce the ion around the lines, which will increase the electric field and the ion current density and influence the environment nearby. Based on the finite-element method, an iterative algorithm to analyze the electric field and ...

Corona power loss, electric field, and current density profiles in bundled horizontal and vertical bipolar conductors In this paper, computation of the corona current and, hence, the corona power loss associated with bipolar high-voltage direct current (HVDC) conductors is... ZM Al-Hamouz - 《...
The effects on this phenomenon of both temperature and voltage were studied. Electrostatic pressure and field-stimulated growth of the ice/metal contact area appear to be the most likely causes of this effect.关键词: Experimental/ electric current electric field effects ice sliding friction steel/ ...
