friction peak has been found in iron at about lOOoK, and possibly in molybdenum at about 300°K. These internal friction peaks occur at temperatures corresponding to the ductile to brittle transition of these materials in slow tension tests. The possible role of hydrogen in causing the 100°K peak in
We measured the low temperature internal friction of a variety of hydrogenated amorphous, nanocrystalline, polycrystalline, and epitaxial silicon thin films. Most of the films studied are prepared either by hot-wire chemical-vapor deposition (HWCVD) or by plasma-enhanced chemical-vapor deposition (P
