The concept uses tiny triangular structures to control «phonons,» quantum - mechanical phenomena that describe how vibrations travel through a material's crystal structure.
Until now, heat transport in nanostructured materials has largely been controlled by introduction of atomic - scale impurities, interfaces, surfaces and nanoparticles that reduce heat flow by scattering the phonons diffusely.
Their research has also introduced a new dimension to the emerging field of «phononics» which is the controlling and manipulating of heat flow with phonons (particles which transmit heat within solid materials).
Resume: Progress in the last few decades in nano - scale thermal transport has enabled a significant degree of control over heat and sound propagation by lattice vibrations - phonons.
The capability to tune the acoustic phonon dynamics in technologically relevant group IV nanostructures provides a promising prospect to control the propagation of acoustic and thermal phonons with great implications on nanoscale hypersound and thermal transport.
Progress in the last few decades in nano - scale thermal transport has enabled a significant degree of control over heat and sound propagation by lattice vibrations - phonons.
In comparison, the control of phonons is still falling short.
