<p>Compounds having the formula (MX3)n M'X4-n wherein M and M' are different Group 4A atoms, at least one of M and M' is silicon, X is hydrogen, halogen or mixtures thereof, and n is an integer between 1 and 4, inclusive, are useful as deposition feedstock materials in the formation of hydrogenated amorphous silicon alloys useful in the fabrication of photovoltaic and other electronically active devices. Dopants having the formula (SiX3)m L X3-m wherein L is a Group 5A atom selected from the group of phosphorous, arsenic, antimony and bismuth, X is hydrogen, halogen or mixtures thereof and m is an integer between 1 and 3, inclusive, are useful in the fabrication of negatively-doped hydrogenated amorphous silicon alloys useful in the fabrication of photovoltaic and other electronically active devices. Dopants having the formula YJX2 wherein Y is halogen or carbonyl, J is a Group 3A atom and X is hydrogen, halogen or mixtures thereof, are useful in the formation of postively-doped hydrogenated amorphous silicon alloys useful in the fabrication of photovoltaic and other electronically active devices.</p> |
