摘要：
An embodiment of the present invention improves the fabrication and operational characteristics of a type-II superlattice material. Layers of indium arsenide and gallium antimonide comprise the bulk of the superlattice structure. One or more layers of indium antimonide are added to unit cells of the superlattice to provide a further degree of freedom in the design for adjusting the effective bandgap energy of the superlattice. One or more layers of gallium arsenide are added to unit cells of the superlattice to counterbalance the crystal lattice strain forces introduced by the aforementioned indium antimonide layers.
