Abstract

The invention provides a method for preparing amorphous semiconductors by (a) activating a semiconductane gas using a activator to produce mononuclear, reactive fragments or gaseous condensation products which serve as precursors for the deposition of an amorphous semiconductor; and (b) controlling the temperature of the activator and the flow rate and temperature of the semiconductane gas so that it does not completely decompose upon the activator.
