Sentences with phrase «of electrons in the material»

As a final result, you get an image of the location of most of the electrons in the material at a specific time delay.

They then added a layer of graphene in order to apply an electric voltage with which the density of electrons in the material could be controlled.

Thermoelectrics work when they connect something hot with something cold: «The thermal motion of the electrons in the material depends on the temperature,» explains Bühler - Paschen.

«If you do this many times, for many photons, you can slowly build up an image of the distribution of the electrons in the material.

«If we want to use light to control the properties of electrons in a material, then we need to know exactly how the electrons will react to light pulses,» Ivanov explains.

Unlike in the standard Fermi liquid model, the quantum mechanical spins of some electrons in the material are linked together in an FFL.

Experimentalists looking for new topological insulators have conventionally relied on a laborious process that involves calculating the possible energies of electrons in each material to predict its properties.

To observe ultrafast electron motions in space and time, one needs to measure the position of electrons in the material with a precision of the order of 0.1 nm (0.1 nm = 10 - 10 m), roughly corresponding to the distance between neighboring atoms, and on a sub-100 fs time scale (1 fs = 10 - 15s).

«This is unambiguous smoking - gun evidence to confirm theoretical predictions for the conduction of electrons in these materials,» said Purdue University doctoral student Yang Xu, lead author of a paper appearing this week in the journal Nature Physics.

The Kondo effect occurs when the presence of a magnetic atom (an impurity) causes the movement of electrons in a material to behave in a peculiar way.

The team used SLAC's LCLS to measure atomic vibrations and ARPES to measure the energy and momentum of electrons in a material called iron selenide.

While most magnetic materials are «collinear», meaning that the magnetic orientations of the electrons in the materials are arranged either in the same or opposite directions — that is, what we think of as «north» or «south» — this was not the case for the affected nickelate.

Eiji Saitoh of Keio University in Yokohama, Japan, and his collaborators found that heating one side of a magnetized nickel - iron rod changes the arrangement of the electrons in the material according to their spins.
