英文摘要	On the basis of the finite element approach, we systematically investigated the strain field distribution of conical-shaped inas/gaas self-organized quantum dot using the two-dimensional axis-symmetric model. the normal strain, the hydrostatic strain and the biaxial strain components along the center axis path of the quantum dots are analyzed. the dependence of these strain components on volume, height-over-base ratio and cap layer (covered by cap layer or uncovered quantum dot) is investigated for the quantum grown on the (001) substrate. the dependence of the carriers' confining potentials on the three circumstances discussed above is also calculated in the framework of eight-band k (.) p theory. the numerical results are in good agreement with the experimental data of published literature.
