ABSTRACT:
Compounds having the formula (MX.sub.3).sub.n M'X.sub.4-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, can be activated by dehydrogenation or dehalogenation. These compounds 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 (SiX.sub.3).sub.m L X.sub.3-m wherein L is a Group 5A atom selected from the group of phosphorus, arsenic, antimony and bismuth, X is hydrogen, halogen or mixtures thereof and m is an integer between 1 and 3, inclusive, can be activated by dehydrogenation or dehalogenation. These compounds 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 YJX.sub.2 wherein Y is halogen or carbonyl, J is a Group 3A atom and X is hydrogen, halogen or mixtures thereof, can be activated by dehydrogenation or dehalogenation. These compounds are useful in the formation of positively-doped hydrogenated amorphous silicon alloys useful in the fabrication of photovoltaic and other electronically active devices.
