Superlattices
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Superlattices are artificially structured materials composed of alternating layers of different substances, typically at the nanometer scale. These multilayered structures exhibit unique electronic, optical, and mechanical properties that differ significantly from their bulk counterparts. Superlattices are commonly used in semiconductor technology, optoelectronics, and nanotechnology to tailor material characteristics for specific applications.
