Using an empirical scheme, the atomic structure of a new exotic class of silicon nanoclusters was elaborated upon the central icosahedral core (Si−IC) and pentagonal petals (Si−PP) growing from Si−IC vertexes. It was shown that Si−IC/Si−PP interface formation is energetically preferable. Some experimental observations of silicon nanostructures can be explained by the presence of the proposed objects. The extended Huckel theory electronic structure calculations demonstrate an ability of the proposed objects to act as nanoscale tunnel junctions.
