What is Thin Film?
What is Thin Film?
- Needs substrate
-
- Can not stand by alone
- Characteristics depend on the surface condition of the substrate
- Enough thin to change properties
-
- Thin film features mostly comes from its thickness
- Formed through atom/molecular state
-
- Formed after decomposing the materials into atomic/molecular scale by physical and/or chemical measure
Comparison between Thin film and Human
Features of Thin Film
| Properties | Extraordinary Phenomena | Application |
|---|---|---|
| Electron Transportation | Increase of resistivity Decrease of temperature coefficient | Thin film resistors |
| Super Conductivity | Amplitude and maximal of electro-magnetic characteristics | Josephson device |
| Magnetism | Tunnel effect | Thin film resistors |
| Optics | Dependence of reflection and absorption rate to wavelength | Anti-reflection coating |
