Calculation of strain energy density and relative strain energy in QWR nanostructures using bimaterial BEM formulation

摘要：

In this paper, we derive bimaterial Greens functions and apply our bimaterial boundary element method (BEM) to calculate the strain energy density and the relative strain energy in quantum wire (QWR) nanostructures. The results show that the magnitude of the relative strain energy increases with increasing depth of the QWR with respect to the surface of the substrate and for a QWR isosceles triangle free standing on the surface of the substrate, the magnitude of the relative strain energy increases with increasing base angle of the triangle QWR. These results could be useful to the control of the QWR shape and size in epitaxial growth.
