Thin Film

Thin Film

A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness.Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer.

Thin Film is used for varius applications like

• Decorative coatings
• Optical coatings
• Protective coatings
• Electrically operating coatings
• Thin-film photo voltaic cells
• Thin-film batteries
