Raman amorphous
Webbtronic structure of amorphous carbon and then the nature of Raman scattering in disordered carbons, both of which show unique features. We then present a three-stage … WebbThe broad and weak Raman bands corresponding to films B) and C) indicate the presence of a high degree of amorphous phase. The morphology and structural investigations show that RF sputtering from a V 2 O 3 target led to a more crystalline structure of the films deposited in process (A) comparatively with the (B) and (C) processes.
