Claim Text:
1. A semiconductor structure comprising: a substrate comprising a first crystalline semiconductor material; a dielectric layer, above the substrate, defining an opening, wherein the opening includes non-crystalline sidewalls; a second crystalline semiconductor material at least partially filling the opening; a crystalline interlayer between the substrate and the second crystalline semiconductor material, wherein the non-crystalline sidewalls extend continuously from an uppermost surface of the substrate to above the crystalline interlayer all the way to an uppermost surface of the second crystalline semiconductor material, and wherein the uppermost surface of the second crystalline semiconductor material is coplanar with an uppermost surface of the opening wherein: the first crystalline semiconductor material and the second crystalline semiconductor material are lattice mismatched; and the crystalline interlayer comprises an oxygen compound.
