Abstract:
1. A method of manufacturing a single-phase, group-III Nitride semiconductor alloy, the method comprising: providing a metal source; providing a nitrogen source; providing a substrate; establishing an average reaction temperature range from about 250° C. to about 850° C. in a space; introducing a nitrogen flux at a nitrogen flow rate into the space; introducing a first metal flux at a first metal flow rate into the space; establishing a plasma in the space; and maintaining an adlayer thickness of nitrogen and a first metal on a growth surface of the substrate that is less than a surface segregation onset dose by periodically stopping and restarting the first metal flux according to a first flow duty cycle to produce the group-Ill Nitride semiconductor alloy.
