The spatial distributions of the density of valence electrons and their cross sections within the cell, the distribution of the density of electronic states, and electric charges in the vicinity of the silicon atoms in different atomic environments are calculated. It is investigated how changes in the electronic subsystem of investigated objects influence the change of their properties from non-conducting to conducting ones.&nbsp;</p> ER -
