Introduction to Titanium Thin Films

Titanium (Ti) is a popular metal for use in thin film form due to its excellent mechanical, electrical and optical properties. Ti thin films find their applications in a wide range of fields including microelectronics, sensors, solar cells, and biomedical implants.

Properties of Ti Thin Films

• High melting point (1668°C)
• Low density (4.5 g/cm³)
• Good mechanical strength and ductility
• High resistance to corrosion and oxidation
• Good adhesion to a wide range of substrates

Comparison of Ti with other Metals

Titanium thin films are known for their high strength-to-weight ratio, good biocompatibility, and resistance to corrosion, making them a preferred choice over other metals such as copper, aluminum, and nickel.

Crystal Structure of Titanium Metal

Titanium has a hexagonal close-packed (HCP) crystal structure in its pure metal form. However, in thin film form, the crystal structure can be affected by the substrate and deposition conditions.
