Dear PWSCF user,
I would like to know weather PWSCF can calculate low energy phonon modes
(call it acoustic phonons) for semiconductor nanostructure system like
Silicon (size nearly 5 nm). If we see Raman spectra then some of low
frequency mode in the range of 5- 50 cm-1. These modes are important in
How one can proceed to calculate?
Thanks in advance.
