Paper Abstract

In an effective mass approximation a calculation of an energy spectrum of quantum dots (QD) is carried out. Quantum dots of an spherical and cylindrical forms (the height is much less then radius-disc or tablet nanocluster) are analyzed. Numerical constants of Ge-Si heterostructure are used in calculation. Difference of hole effective mass in Ge and Si is taken into account. In envelope wave function approximation an estimation of photoionization cross-section of the pherical cluster ground state is carried out. For a tablet cluster estimation of matrix elements ratio of ground state photoionisation by electro-magnetic radiation with E vector along and perpendicular cluster axis is carried out.
