Abstract
We present results on the problem of surface instability induced by a uniaxial stress. We show that the surface modulation leads to a cellular structure with deep grooves, and a coarsening occurs in that wide cells grow at the expense of thin ones. We present both numerical and analytical results, and discuss the implication of this instability in the formation of quantum dots. We suggest a mechanism that may explain the experimental fact according to which quantum dots occur rather for compressive than for a tensile strain without evoking anharmonicity.
