About my Research:
My research deals with elasticity problems
in the nanometer scale, near the lower edge of the continuum mechanics.
Using
Scanning Tunneling Microscopy (STM) I can see both lateral and vertical atomic
displacements of the surface atoms. These displacements are due to internal
stress source such as steps, dislocations and more, Or due to external stress
source as epitaxial deposition on top of the surface. These atomic
displacements compared to computational simulations based on Finite Elements
Method.
Using
atomic scale Technology one can give answer to questions such as the variation
in mechanical properties of the surface from those of the bulk of the same
material. Or, how can we understand the elastic mechanism that causes quantum
Dots arrays to line up laterally and vertically in multi Layers structure.
