Classification: CPC H | IPC H

Claim 0:
1. A semiconductor structure, comprising:
a first conductivity type region comprising a first superlattice; and
an i-type active region adjacent to the first conductivity type region, the i-type active region comprising an i-type superlattice;
wherein:
the first conductivity type region is a p-type region or an n-type region;
the first superlattice is comprised of a plurality of first unit cells;
the i-type superlattice is comprised of a plurality of i-type unit cells;
each of the plurality of first unit cells comprises a first set of at least two distinct substantially single crystal layers;
each of the plurality of i-type unit cells comprises a second set of at least two distinct substantially single crystal layers;
an average alloy content of the plurality of the first unit cells and the i-type unit cells is constant along a growth direction; and
a combined thickness of the second set of at least two distinct substantially single crystal layers is thicker than a combined thickness of the first set of at least two distinct substantially single crystal layers.
