Application

Sputtering is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic particles. The extreme miniaturization of components in the semiconductor and electronics industry requires high purity sputtering targets for thin film deposition.

Nanocomposite Coatings with Tunable Properties Prepared by Atomic Layer Deposition

Spintronics offer breakthroughs over conventional memory/logic devices with lower power, leakage, saturation, and complexity.

The properties of many devices are limited by the intrinsic properties of the materials that compose them.
