The Analytical Study of Electronic and Optical Properties of Pyramid-Like and Cone-Like Quantum Dots
The analytical expressions for electron wave function of pyramid-like and cone-like quantum dot located on the semiconductor surface are obtained. The energy spectrum of electron states in the quantum dots is calculated. The dependence of energy levels on the angle at the vertex of
an edge-shaped nanodots is studied. The distribution of electron density for different electronic states is calculated for each case. The dependence of function of linear response to the external field on vertex angle is calculated in the frame of proposed approach. The local field distributions
for both pyramid- and cone-like particles are calculated.
