Abstract:
1. A method for depositing multiple materials on a target, the method comprising the steps of: atomizing a first material to form a first aerosol comprising first droplets, the first droplets comprising the first material; atomizing a second material different from the first material to form a second aerosol comprising second droplets, the second droplets comprising the second material; merging a first droplet stream comprising the first aerosol and a second droplet stream comprising the second aerosol to form a merged droplet stream, the merged droplet stream comprising the first droplets and the second droplets such that the first droplets and the second droplets are transported together without reacting the first material with the second material; surrounding the merged droplet stream with an annular flow of a sheath gas in a generally conical region, thereby forming a combined stream; focusing the combined stream; transporting the combined stream through a nozzle; and depositing the first and second droplets on a target; wherein the first and second materials do not react until they are deposited on the target; and wherein the conical region is oriented to converge the combined stream toward a central axis of the apparatus prior to the depositing step.
