We review recent progress in the growth and characterization of Si 1− x Ge x islands and Ge
dots on (001) Si. We discuss the evolution of the island morphology with Si 1− x Ge x …

Mechanical instabilities that cause periodic wrinkling during compression of layered
materials find applications in stretchable electronics,, and microfabrication,,,, but can also …

Strain plays a critical role in the properties of materials. In silicon and silicon–germanium,
strain provides a mechanism for control of both carrier mobility and band offsets. In materials …

Two buckling modes have been observed in thin films: buckle delamination and wrinkling.
This letter identifies the conditions for selecting the favored buckling modes for elastic films …

A stressed thin film on a soft substrate can develop complex wrinkle patterns. The onset of
wrinkling and initial growth is well described by a linear perturbation analysis, and the …

We examine the buckling of a thin elastic film bonded to a much thicker viscous substrate
undergoing compression at a fixed rate. Experiments show two distinct buckling modes. At …

We study experimentally the main features of wrinkles that form in an initially stretched and
flat elastic membrane when subjected to an axi-symmetric traction force at the center. The …

This paper develops a model for evolving wrinkles in a bilayer thin film consisting of an
elastic layer and a viscoelastic layer. The elastic layer is subjected to a compressive residual …

This paper presents a nonlinear mathematical model for evolution of wrinkle patterns of an
anisotropic crystal film on a viscoelastic substrate layer. The underlying mechanism of …

We conduct a finite element computational study of the dynamics of a thin elastic film
bonded to a much thicker viscous substrate undergoing compression at a fixed rate. The …
