Yes, of course. Raman is a classical method to judge your crystalline quality so if you grow your layers differently the quality will vary as well therefore affecting phonon frequencies.

I have never sputtered sulfides so I can't tell you what's good but it definitely makes sense.

Edit: I see that @Thomas Breuer posted simultaneously. Good reference list right there.

Dr Azeez Barzinjy

I also agree with Thomas Breuer ,

Raman shift always work for crystalline quality .
