They found that different molecular combinations altered the electronic structure
of the quantum dot in unique ways.
By intricately manipulating matter on a nanoscale, the team etched the unique 2D electronic structure
of graphene onto a semiconductor material called gallium arsenide.
For example, it was recently realised that isolated touching points of these bands can be stabilised by certain crystalline symmetries, creating so-called Dirac fermions in the bulk electronic structure
The INDO method applicable to the electronic structure
calculation of lanthanide compounds.
He discusses molecular structure and electronic structure
, including x-ray and electron spectroscopy methods; the crystallographic structure and microstructure determination, including diffraction, reflectometry, and scattering; the imaging and other real space mapping methods based on x-rays; the anomalous dispersion of chemical elements and uses in elemental, chemical, and orbital x-ray contrast variation; the surface and bulk sensitivity of the methods; organic and bio-organic samples; x-ray electrochemical case studies of batteries, fuel cells, and photoelectrochemical cells; and how x-ray based data can match the conductivity data from some materials.
It's fundamentally interesting and important because it's such a curious thing," says physicist David Petrosyan of the Institute of Electronic Structure
& Laser at the Foundation for Research and Technology-Hellas in Heraklion, Greece.
Computed spin densities and atomic charges reveal various degrees of influence of the axial ligands on the Cu-porphyrin electronic structure
, which may be related to the notably different changes induced by each ligand (imidazole, nitrite, guaiacol and ABTS) on the EPR superhyperfine splitting, but with an unexpectedly strong dependence on choice of the computational methodology.
We investigated the effect of a surface defects, such as losing ligands and external charge, on the electronic structure
and the energy transfer between methyl passivated silicon quantum dots (QDs).
In the ever-expanding universe of compounds prepared to date," the article reads, "it is remarkable that a two-carbon ion with an apparently simple electronic structure
could have eluded structural characterization until now.
An international electronic structure
(in English) gathering Tunisian skills will also see be created, according to the minister.
Their electronic structure
or color can be changed by electron beams without changing their outward structure.
Chen said the swift development of graphene and topological insulators has raised questions as to whether there are 3D counterparts and other materials with unusual topology in their electronic structure
