Deformation Instabilities in a Thin Plastic Film on an Elastic Substrate Due to Strain Mismatch.

摘要

The study of thin film structures from the point of view of solid mechanics is becoming increasingly relevant to various areas of modern technology. Ultra-thin to moderately thick metallic and organic films grown over relatively massive solid substrates and more complicated ones involve multi-layers of several films with different chemical, electrical, optical, thermal and mechanical properties. There are various method used to grow films, but chemical vapor deposition and electron beam deposition are the two most commonly used techniques. Inherent to these deposition methods is the introduction of residual and thermal stresses in the thin films. (js)
