Nanotubes for charge storage - Towards an atomistic model
(Pergamon-Elsevier Science Ltd, 2015-04)
We examine the insertion of alkali and halide ions into narrow nanotubes of graphite and gold by density functional theory (DFT). For tubes with diameters less than about 10 Åthe optimum position of the ion is in the center ...

Optimizing feature selection through binary charged system search
(2013-09-26)
Feature selection aims to find the most important information from a given set of features. As this task can be seen as an optimization problem, the combinatorial growth of the possible solutions may be inviable for a ...
Electrostatic theory for imaging experiments on local charges in quantum Hall systems
(Elsevier Science BvAmsterdamHolanda, 2006)
Image effects in transport at metal-molecule interfaces
(American Institute of Physics, 2015)
We present a method for incorporating image-charge effects into the description of charge transport through molecular devices. A simple model allows us to calculate the adjustment of the transport levels, due to the ...
Screening of ions in carbon and gold nanotubes: A theoretical study
(Elsevier, 2014-05)
We examine the insertion of alkali ions into narrow nanotubes of graphite and gold by density functional theory. The surrounding tubes screen the ionic charge very effectively; the resulting image energy compensates well ...
Image potential state Influence on Charge Exchange in Li+ - Metal Surface Collisions
(American Chemical Society, 2014-04)
The energy dependence of the neutral fraction of ions scattered by metal surfaces is observed to be affected by the presence of energy gaps and surface states in their surface band structure. The effect is more dramatic ...
Charge density alterations in human hair fibers: An investigation using electrostatic force microscopy
(2006-04-01)
A new method for high-resolution analyses of hair surface charge density under ambient conditions is presented in this paper. Electrostatic force microscopy (EFM) is used here to analyze changes in surface charge density ...
