Controlling acoustic transport in hypersonic crystals

Center for Nanoscale Materials users from Toyota Research Institute of North America, working with CNM's Nanophotonics Group, have determined that bulk coherent acoustic vibrations are heavily damped by scattering from radially ...

Tiny tool measures heat at the nanoscale

How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials ...

Large wave-vector phonon modes in silicon nanomembranes

(Phys.org) —Modified large wave-vector phonons in semiconductor membranes via hard X-ray thermal diffuse scattering (TDS) were observed that provide new insight into the fundamental thermal and electronic properties of ...

Quantum information motion control is now improved

Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in the European Physical Journal B. This ...
