【Abstract】 The stress and strain distributions of simplified and idealized two-,one- and zero-dimensional semiconductor materials, i.e. quantum well,quantum wire and quantum dot are investigated based on the isotropic theory of elasticity,and the differences among the stress,strain and strain energy distributions for the materials are discussed. The results can help us to understand qualitatively the stress,strain and strain energy distributions of the more complicated shapes and structures of low-dimensional semiconductor materials.更多还原
