Claim 9:
10. A 3D-integrated electrical device, comprising:
an integrated circuit having at least one vertical interconnect and a bonding layer; and
the electrical device according to claim 9, the electrical device being a photodetector in which:
the substrate includes a photoconductor layer comprising Hg1-xCdxTe;
the aluminum nitride buffer layer is a neutral stress layer;
the aluminum nitride tensile stress layer overlying at least a portion of the aluminum nitride neutral stress layer;
the compressive stress layer is a bonding layer at least partially overlying the aluminum nitride tensile stress layer;
and further comprising at least one vertical interconnect;

wherein the bonding layer of the readout integrated circuit is bonded to the bonding layer of the electrical device, and wherein the at least one vertical interconnect of the readout integrated circuit is electrically connected to the at least one vertical interconnect of the electrical device.
