Abstract
A ternary superlattice structure includes a substrate and periodic layer structure on the substrate and having alternating infrared absorbing semiconductor materials having a first layer of InAsSbternary alloy material, and a second layer of InZAs ternary alloy material, wherein Z is Ga or Al, wherein x is in a range of greater than zero and less than one, wherein y is in a range of greater than zero and less than one, and wherein a thickness of each of the first and second layers are substantially similar and configured to absorb light in a predetermined spectral band and prevent trapping of carriers in any particular layer. In examples, y is in a range from about 0.05 to about 0.35, and x is in a range of about 0.2 to about 0.8.
