Sentences with phrase «electronic band structures»

The resulting high quality spectra and her understanding of the special symmetry of graphite allowed Dresselhaus to characterise its electronic band structures far more accurately than had previously been achieved.

Published by the Condensed Matter research group at the Nordic Institute for Theoretical Physics (NORDITA) at KTH Royal Institute of Technology in Sweden, the Organic Materials Database is intended as a data mining resource for research into the electric and magnetic properties of crystals, which are primarily defined by their electronic band structure — an energy spectrum of electrons motion which stem from their quantum - mechanical properties.

In this sense, a «valley» refers to the region in an electronic band structure where both electrons and holes are localized, and «valley polarization» refers to the ratio of valley populations — an important metric applied in valleytronics research.

These early experiments helped to map out the electronic band structure of these materials, critical to further understanding the unique properties they might possess.

Not exact matches

A modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure.

Theory and experiment indicate that the suitable phenomenological electronic structure model of the CuO layers is that of the one - band Hubbard model.

Quantum confinement of the electronic wave function allows to open a finite band - gap in the graphene electronic structure.

Adopting the scheme of chemical disorder, which has been proved to successfully capture the variety of eumelanin protomolecules, we show that (1) the formation process of eumelanin protomolecules from the constituting monomers is generally hindered in a solvent environment with respect to vacuum and (2) key factors in improving the adhesion properties and band lineup of the molecules on an inorganic interface are the molecular electronic state and the planarity of their structures.

Employing a strategic combination of detailed electronic structure calculations, combinatorial materials synthesis, and both traditional and high - throughout photoelectrochemistry measurements, the JCAP team identified earth - abundant copper and manganese vanadate complex oxides that meet highly demanding requirements for photoanodes: low band gap energy, stability under highly oxidizing conditions, and valence band alignment with respect to OER.
