Claim 0:
1. A thin-film structure comprising:
a plurality of superlattice periods, each superlattice period comprising a first material layer disposed adjacent to a second material layer;
wherein the plurality of superlattice periods comprises:
a first superlattice period wherein a thickness of a first material layer of the first superlattice period is x and a thickness of a second material layer of the first superlattice period is 3x;
a second superlattice period disposed adjacent the first superlattice period, wherein a thickness of a first material layer of the second superlattice period is x and a thickness of a second material layer of the second superlattice period is 4x;
a third superlattice period disposed adjacent the second superlattice period, wherein a thickness of a first material layer of the third superlattice period is x and a thickness of a second material layer of the third superlattice period is 5x;
a fourth superlattice period disposed adjacent the third superlattice period, wherein a thickness of a first material layer of the fourth superlattice period is x and a thickness of a second material layer of the fourth superlattice period is 6x; and
a fifth superlattice period disposed adjacent the fourth superlattice period, wherein a thickness of a first material layer of the fifth superlattice period is x and a thickness of a second material layer of the fifth superlattice period is 7x.
