Ion Microscopy on Diamond
Because of its physical properties (strong radiation hardness, wide energy gap with a consequent extremely low dark current, very large electron and...
-
Raman Spectroscopy and Optical Properties of Amorphous Diamond-Like Carbon Films
The Raman spectroscopy and optical characterization of amorphous hydrogen-free diamond-like carbon films is described. The samples were prepared by...
-
Correlation Between Local Structure and Film Properties in Amorphous Carbon Materials
A discussion of the various amorphous carbon and amorphous hydrogenated carbon films is presented. A link between sp 2, sp...
