Abstract:
1. A method of producing a material that mimics the properties of an AlInAsSb quaternary material and is lattice matched to InAs material, the method comprising: providing an InAs layer; growing a plurality of group III-V ternary layers, each ternary layer having two group III elements and one group V element; and growing a plurality of group III-V quarternary layers, each quarternary layer having two group III elements and two group V elements; wherein the group III-V ternary layers are separated from each other by a single group III-V quarternary layer; wherein each group III-V ternary layer is in direct contact with a group III-V quarternary layer; and wherein at least one group III-V ternary layer is grown in direct contact with the InAs layer.
