Abstract: | A new allotropic form of amorphous silicon with sp hybridization of the valence electrons is discovered. The new material consists of linear chains of atoms. A small fraction
of the atoms are in the sp
2 state. Acting as bridges, these atoms couple the linear chains into a single random network. This conclusion is based on
an analysis of experimental data on the effect of annealing and ion implantation on the structure of the short-range order
and the properties of amorphous-silicon films obtained by different methods.
