Perhaps you should try some spelling variations:
"surface and interfaces, thick films" » "surface and interfaces, thick film"
"surface and interfaces, thin films" » "surface and interfaces, think films", "surface and interfaces, than films"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"surface and interfaces, thick films\") OR (\"surface and interfaces, thin films\"))".
• Removing quotes may allow a broader search: (( surface and interfaces, thick films ) OR ( surface and interfaces, thin films )).
• Adding a wildcard symbol may retrieve word variants: (("surface and interfaces, thick films") OR ("surface and interfaces, thin films"))*.
