Relaxation of a Strained Elastic Film on a Viscous Layer
نویسندگان
چکیده
Experiments were conducted with SiGe film islands on a layer of borophosphorosilicate glass (BPSG). Initially the SiGe is under compression. Upon annealing, the glass flows and the SiGe islands relax by both inplane expansion and wrinkling. This paper provides a twodimensional (2D) model for inplane expansion. The results from the model are compared with the experiments with small SiGe islands. The effect of winkling, which is ignored in the present model, is discussed qualitatively.

Wrinkling of a compressed elastic film on a viscous layer
A compressively strained elastic film bonded to a viscous layer can form wrinkles. The present study provides a theoretical model for the wrinkling process. The elastic film is modeled with the nonlinear theory of a thin plate subject to in-plane and out-of-plane loads. The flow of the viscous layer is modeled with the theory of lubrication. The interface between the elastic film and the viscou...
متن کاملMechanisms of Dislocation Nucleation in Strained Epitaxial Layers
Using molecular static simulations we have studied possible mechanisms of stress relaxation with misfit dislocation nucleation in strained heteroepitaxial layers. Two-dimensional models of atomic systems with Lennard-Jones type potential were considered. Combination of total energy minimization with spherical repulsion and nudged elastic band calculation allowed us to study possible transitions...
متن کاملInstability of a compressed elastic film on a viscous layer
A flat, compressed elastic film on a viscous layer is unstable. The film can form wrinkles to reduce the elastic energy. A linear perturbation analysis is performed to determine the critical wave number and the growth rate of the unstable modes. While the viscous layer has no effect on the critical wave number, its viscosity and thickness set the time scale for the growth of the perturbations. ...
متن کاملGrowth Instability of Strained Film: An Elastic Green’s Function Force Monopole Approach
We analyze the growth stability of an epitaxial strained film on a flat substrate by the elastic Green’s function force monopole approach. We calculate and compare the strain energies and growth instability of three different forms of surface undulations: sinusoidal waviness, surface faceting and island formation. In general, the instability occurs beyond a critical length scale, in agreement w...
متن کاملKinetic wrinkling of an elastic film on a viscoelastic substrate
A compressed elastic film on a compliant substrate can form wrinkles. On an elastic substrate, equilibrium and energetics set the critical condition and select the wrinkle wavelength and amplitude. On a viscous substrate, wrinkle grows over time and the kinetics selects the fastest growing wavelength. More generally, on a viscoelastic substrate, both energetics and kinetics play important roles...
