Image Methods for Electrostatic Potentials
Image method is a classical method for finding electrostatic potentials in dielectric or conducting objects with special geometries. The image method provides simple and analytical formulas to represent the reaction field on a charge in an object as a result of the polarization effect from the surrounding material. In this paper, we will provide an overview of the classical results of image met...
متن کاملCharges fit to electrostatic potentials. II. Can atomic charges be unambiguously fit to electrostatic potentials?
The present work examines the conditioning of the least-squares matrix for obtaining potential derived charges and presents a modification of the CHELP method for fitting atomic charges to electrostatic potentials. Results from singular value decompositions (SVDs) of the least-squares matrices show that, in general, the least-squares matrix for this fitting problem will be rank deficient. Thus,...
متن کاملThe measurement of electrostatic potentials in core/shell GaN nanowires using off-axis electron holography
Core-shell GaN nanowires are expected to be building blocks of future light emitting devices. Here we apply off-axis electron holography to map the electrostatic potential distributions in such nanowires. To access the cross-section of selected individual nanowires, focused ion beam (FIB) milling is used. Furthermore, to assess the influence of FIB damage, the dopant potential measured from an ...
متن کاملSome Observations Concerning Electronic Densities, Electrostatic Potentials and Chemical Potentials
The hypothesis that the electronic density distribution in a molecule is qualitatively similar to the nuclear potential is shown . to be in error in at least two cases-oxirane and cubane-although it does hold true in a' number of other systems. Its emphasis upon the dominant role played by electrostatic internctions with the nuclei is consistent with some approximate molecular energy formulas. ...
متن کاملCarbon nanotube multi-electrode array chips for noninvasive real-time measurement of dopamine, action potentials, and postsynaptic potentials.
Multi-electrode arrays (MEAs) can be used for noninvasive, real-time, and long-term recording of electrophysiological activity and changes in the extracellular chemical microenvironment. Neural network organization, neuronal excitability, synaptic and phenotypic plasticity, and drug responses may be monitored by MEAs, but it is still difficult to measure presynaptic activity, such as neurotrans...
