Mechanical properties of microspring thin films fabricated by glancing angle deposition (GLAD)

Unique thin film microstructures have been fabricated with the Glancing Angle Deposition (GLAD) technique. These porous, thin films can be engineered with a variety of many different morphologies to sub-micron dimensions. Mechanical properties of helically structured thin films were studied with a nanoindentation technique, allowing properties such as the spring constant to be determined. Present work on the study of these "microspring-beds" is ongoing, and includes the determination of resonant frequencies and application to potential devices.
