Ballistic Deposition
Term: Ballistic Deposition
Category: Coating Method
Definition: A form of physical vapor deposition utilized to manufacture thin films or any coating. This technique includes the process of ejecting particles (atoms, molecules, or nanoparticles) from an origin, traveling along ballistic (straight-line) routes, and striking the substrate where the particle sticks upon reaching the substrate. The resultant thin film possesses either a columnar or porous microstructure owing to the random shadowing effect that occurs during the deposition of the material.
Common Uses:
- Fabrication of thin-film coatings in electronics, optics, and sensors
- Production of nanostructured surfaces for catalysis or biomedical applications
- Creating porous or columnar coatings with controlled mechanical and optical properties
- Development of surface-functionalized materials for hydrophilic or hydrophobic treatments
