Electronic energy level patterns of small stable, pre-designed clusters composed of , and atoms are calculated using a multi-configuration self-consistent field approximation. The structure and composition of the clusters are chosen to reflect their formation in confinement or on surfaces. Manipulations with these parameters permit to engineer computationally clusters with pre-designed electronic properties. Such virtually synthesized atomic clusters can serve as prototypes for experimental sub-nanoscale heterostructure (SNHS) units. Stability of such clusters was confirmed recently by experiment.
