Abstract:
A rapid-temperature pulsing anneal (RPA) method of fabricating a thin film of layered superlattice material comprising steps of:providing a substrate; providing a precursor containing a plurality of metals in suitable amounts for forming a layered superlattice material upon heating said precursor: applying said precursor to said substrate to form a coating; and applying a first rapid-temperature pulse to said coating at a first hold temperature in a range of from 400Â° C. to less than 800Â° C. for a first holding time at said first hold temperature in a range of 5 seconds to 10 minutes; and then, without an intervening application of said precursor, applying a second rapid-temperature pulse to said coating at a second hold temperature in a range of from 400Â° C. to less than 800Â° C. for a second holding time at said second hold temperature in a range of from 5 seconds to 10 minutes: wherein said first and second rapid-temperature pulsing are conducted in an oxygen-containing atmosphere and are not conducted in a furnace.
