Can atk calculate frequency?
« on: April 14, 2009, 13:24 »
I think atk can't do this directly. Can anyone give some hints? Such as building force constants matrix.
Thanks!

What kind of frequency are you talking about? A phonon-frequency?

Hi,

May be you can use I-V characteristics of a two-probe structure for calculation of phonon frequency (for channel) since the saturation occurs due to phonon scattering. However I do not know the equations exactly, you can find exact eqs in the books.

Cheers,
Serhan
