Title: possibility to decompose the phonon transmission into different modes?
Post by: jcj on April 21, 2016, 22:14

Hi all,

Regarding the phonon transport in ATK(the Green function approach), is it possible to decompose the phonon transmission function by different polarisations, e.g. longitudinal, transverse, flexural modes?

Regards,

Hi,

It is currently not possible to decompose the phonon transmission directly into different polarizations. One way forward might be to calculate the vibrational modes in either the electrode or the device configuration. This gives you (visual) information about the polarizations. You can then compare the energies of the vibrational modes with the energies used in the transmission function.
