Sentences with phrase «of charge carriers»

The motion of individual cells in the body or the transport of charge carriers in energy storage systems can be understood only in the context of the particular environment.

The interaction of charge carriers with magnetic moments is of critical importance but remains a challenge to understand..

We realised that this would allow the microscopic control over the distribution of charged carriers in a bulk semiconductor (e.g. traditional Si microchips) in a nonlinear manner.

However, observing size quantization of charge carriers in graphene nanoconstrictions has, until now, proved elusive due to the high sensitivity of the electron wave to disorder.

Nanoscale imaging of charge carrier transport in bismuth vanadate photoanodes via photoconductive atomic force microscopy.

Nanoscale Imaging of Charge Carrier Transport in Monoclinic Bismuth Vanadate Photoanodes via Atomic Force Microscopy.

Mikhail Katsnelson, a physicist at Radboud University Nijmegen in the Netherlands who did not contribute to the new research, has hypothesized that graphene's ripples are one possible source for scattering of charge carriers in the material.

By choosing a suitable metal and applying an electric field, the concentration of charge carriers in graphene and thus the conduction through the graphene can be influenced.

He is currently working on making direct measurements of the charge carriers in a DFG - funded research project at Freie Universität Berlin.

In particular, his model also explains why a thin, electrically insulating layer between the two materials can even facilitate the transition of charge carriers.

«I calculated the impact of the charge carrier distribution on the electronic states at the interface and how these changes feed back onto the charge carrier distribution,» he explains.

The focus is on recombination of charge carriers because this process is ultimately limiting the performance.

In effect, these quantum wells (where electrons and «holes» both see a lower energy in the «well» layer, hence the name) use their special properties for the confinement of charge carriers (the electrons and holes) in thin layers at a quantum level.

In a recent joint experimental and theoretical work, an international group of physicists demonstrated size quantization of charge carriers, i.e. quantized conductance in nanoscale samples of graphene.

Understanding the doubling of charge carriers in a material may help researchers to better explain and engineer reverse processes, too — such as the technology used in some mobile phone displays that reduces the number of charge carriers (a process known as triplet fusion), said Neaton.
