A new wrinkle in thin film science

Simple, inexpensive way to measure material properties could impact cosmetics, coating and nanoelectronic industries

09-Aug-2007

A remarkably simple experiment devised by scientists yields important information about the mechanical properties of thin films - nanoscopically thin layers of material that are deposited onto a metal, ceramic or semiconductor base. The research results, funded by the National Science Foundation ...
