Strained Layer Superlattice

A Strained Layer Superlattice is a specialized structure made by stacking ultra-thin layers of different semiconductor materials. Because these layers have slightly mismatched atomic sizes, they experience stress or "strain." This strain modifies the electronic properties of the materials, enhancing their performance in devices like lasers and detectors. Essentially, it’s like carefully layering different ingredients to create a tailored material with unique behaviors, benefiting advanced electronic and optical applications through precise control of its atomic composition and structure.
