摘要：

The formation of amorphous silicon using a silicon network polymer as a precursor was investigated. Poly(n-propylsilyne), which has a silicon network structure, was heat-treated in vacuo. The organic side group of poly(n-propylsilyne) disappeared completely and the optical band gap E(g,opt) decreased from 2.91 to 1.29 eV by heat-treatment at 400-degrees-C. The heat-treated poly(n-propylsilyne) showed a far-infrared absorption spectrum similar to amorphous silicon.
