When silane, with more than 0.1% of diborane in the gas mixture, are co-pyrolyzed at temperatures below 540°C, an amorphous silicon-boron alloy is formed. The composition of the solid film was determined by SINS and Auger spectroscopy. The amorphous nature of the films was established by X-ray diffraction, laser Raman spectroscopy, and TEM electron diffraction. Electrical and optical properties of this material are reported. Oxidation and chemical etching of this material were also studied.
