AbstractAbstract
[en] A new modified method based on the charge pumping technique is proposed and adopted to extract the lateral profiles of oxide charges in an advanced MOSFET. A 0.12 μm SONOS device with 50 nm threshold voltage peak is designed and utilized to demonstrate the proposed method. The trapped charge distribution with a narrow peak can be precisely characterized with this method, which shows good consistency with the measured threshold voltage. (semiconductor devices)

AbstractAbstract
[en] It is known that an accelerating charge radiates according to Larmor formula. On the other hand, any DC current following a curvilinear path, consists of accelerating charges, but in such case the radiated power is 0. The scope of this paper is to analyze and quantify how a system of charges goes from a radiating state to a non radiating state when the charges distribution goes to the continuum limit. Understanding this is important from the theoretical point of view and the results of this work are applicable to particle accelerator, cyclotron and other high energy devices.

AbstractAbstract
[en] The charge (Z) distributions from intermediate energy heavy-ion reactions depend upon the multiplicity η of intermediate mass fragments through a factor of the form e-cnZ. Experimentally c starts from zero at low values of the transverse energy Et and reaches a saturation value at high Et. In a liquid-gas phase diagram, c = 0 for the saturated vapor, while c > 0 for the unsaturated vapor. It is suggested that in the c ∼ 0 regime the source evaporates down to a sizable remnant, while for c > 0 the source vaporizes completely. Percolation of a finite system portrays a behavior similar to that observed experimentally

AbstractAbstract
[en] In some special studies (e.g. accelerators, plasmas, etc..), it is necessary to calculate potentials or fields from known charge distributions. In this study, attention is drawn to the following case: mobile charges distributed arbitrarily in a volume almost entirely enclosed by metallic walls consisting of cylindrical cavities connected to one another by cylindrical tubes separated by fixed intervals. These charges induce surface charges on the conducting walls. The surface charges, themselves, induce an electric field, which interacts with the motion of the mobile charges. In order to simplify the studies, special consideration is given to the case of a single fixed charge and a single cylinder and then to a single cavity. A integral equation system is obtained. A FREDHOLM like method is used to solve this system

Dans certaines etudes (par exemple accelerateurs, plasmas, etc...), on a besoin de calculer le potential ou le champ a partir d'une distribution connue des charges. Dans cette etude nous nous interessons plus specialement au cas suivant: On considere des charges mobiles reparties arbitrairement dans un volume a peu pres entierement entoure de parois metalliques. Les parois metalliques sont constituees par des cavites cylindriques reliees entre elles par des tubes cylindriques separes par des intervalles. Ces charges induisent des charges superficielles sur les parois conductrices. Ces charges superficielles induisent elles meme un champ electrique pouvant reagir sur le mouvement des charges mobiles. Pour simplifier on considerera surtout le cas d'une seule charge fixe et d'un seul cylindre puis d'une seule cavite. Nous nous ramenerons a un systeme integral que nous resoudrons en nous inspirant de la methode de FREDHOLMOriginal Title

AbstractAbstract
[en] The common description of the electrostatic force, F(x)=-q∇φ(x), provides an incomplete description of the force on the charge q at a point x when the charge itself induces additional fields, e.g., image charges, polarizations, etc. The equation may be corrected through the introduction of a ''pseudopotential'' formalism. Exploration of some of the elementary properties of the pseudopotential demonstrates its essential simplicity. This simplicity allows it to be incorporated directly into dynamics calculations. We explicitly evaluate the pseudopotential in a number of simple but important cases including the sphere, parallel plates, the rectangular prism, and the cylindrical box. The pseudopotential formalism may be expanded to include extended charge distributions; in this latter form we are able to directly apply the results to experimental measurements
