There exist several techniques allowing to confine the motion of an electron from all three dimensions. The resulting structures, known as quantum dots, promise new opportunities in optoelectronics, and a better understanding of such structures requires incorporating new effects into existing models which inevitably leads to the necessity of using. efficient computational tools. In this paper we analyse computationally the electronic states in quantum dots of cylindrical shape taking into account the influence of the wetting layer. Coupling effects between quantum dot and wetting layer electronic states are demonstrated with numerical examples.
