Graphene, a material which consists of a single layer of carbon atoms, has been celebrated by many as the 'next big thing' in material science. But according to researchers, its thermal properties may ...

Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable magnetic signatures, using neutron spectroscopy on a specially engineered ...

Scientists at Oak Ridge National Laboratory have found that applying an electric field to a specialized ceramic can nearly triple the rate at which heat moves through the material in one direction.

Electron-phonon scattering is often the primary mechanism limiting electron mobility in semiconductors. Thus, changing phonon properties can provide a way to control conductivity. Recently, there has ...

Thermoelectric effect is a phenomenon that utilizes temperature difference to achieve electrical transport, offering potential solutions to the energy and environmental challenges faced by humanity.

Researchers experimentally confirm their 2021 hypothesis that electron-phonon coupling, not electron-electron interactions, ...

The thermal hall effect (THE) is a physical phenomenon characterized by tiny transverse temperature differences occurring in a material when a thermal current passes through it and a perpendicular ...

We show that the otherwise invisible impact of selection rules on three-phonon scattering can be exposed through anomalous signatures in the pressure and temperature dependence of the thermal ...

You may not be able to hear it, but all solid materials make a sound. In fact, atoms ⎯ bound in lattices of chemical ...

Graphene, a material which consists of a single layer of carbon atoms, has been celebrated by many as the "next big thing" in material science. But according to Purdue University researchers, its ...
