Critical Nuclear Charge for Two-Electron Atoms

Physical Review Letters, 2014
The critical nuclear charge Z(c) required to bind a nucleus plus two electrons in a heliumlike atom has recently been an area of active study, resulting in a disagreement with earlier calculations and with the value obtained from the radius of convergence 1/Z* of a 1/Z expansion of the energy.

Critical charge in quantum electrodynamics

Physics of Atomic Nuclei, 2001
The critical nuclear charge Z cr and the critical distance R cr in the system of two colliding heavy nuclei—they are defined as those at which the ground-state level of the electron spectrum descends to the boundary of the lower continuum, with the result that beyond them (that is, for Z>Z

Critical charge concepts for CMOS SRAMs

IEEE Transactions on Nuclear Science, 1995
The dramatic effects of external circuit loading on the heavy-ion-induced charge-collection response of a struck transistor are illustrated using three-dimensional mixed-mode simulations. Simulated charge-collection and SEU characteristics of a CMOS SRAM cell indicate that, in some cases, more charge call be collected at sensitive nodes from strikes ...

Critical nuclear charges forN-electron atoms

International Journal of Quantum Chemistry, 1999
One-particle model with a spherically-symmetric screened Coulomb potential is proposed to describe the motion of a loosely bound electron in a multielectron atom when the nuclear charge, which is treated as a continuous parameter, approaches its critical value.

Critical assessment of charge mobility extraction in FETs

Nature Materials, 2017
Mobility is an important charge-transport parameter in organic, inorganic and hybrid semiconductors. We outline some of the common pitfalls of mobility extraction from field-effect transistor (FET) measurements and propose practical recommendations to avoid reporting erroneous mobilities in publications.

Accurate Linear Model for SET Critical Charge Estimation

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2009
In this paper, we present an accurate linear model for estimating the minimum amount of collected charge due to an energetic particle striking a combinational circuit node that may give rise to a SET with an amplitude larger than the noise margin of the subsequent gates. This charge value will be referred to as SET critical charge (QSET).

Energy agency being dismantled, critics charge

Chemical & Engineering News Archive, 1981
What was hoped to be the first chance to hear the Reagan Administration's plans for the future of the Department of Energy became instead a forum for attacks on Energy Secretary James E. Edwards' handling of employee firings and the rate of prosecution of oil companies for pricing violations.

Sliding charge density waves as a dynamic critical phenomenon

Physica B+C, 1984
The dynamic properties of sliding charge-density waves are discussed in terms of a classical description of impurity pinning, with emphasis on the behavior near threshold considered as a dynamic critical phenomenon. A mean-field model introduced previously [Phys. Rev. Lett.
