Latest Patents

Barrera holds a patent for "Scalable van der Waals superlattices for absorbers and emitters." This invention addresses the challenges associated with the lack of thickness control in exfoliated van der Waals layers. His work enables the creation of uniform, wafer-scale samples that facilitate the engineering of electronic and optical dispersions in stacks of disparate 2D layers. The patent demonstrates systems, methods, and devices that present optical dispersion engineering in a superlattice structure, which includes alternating layers of 2D excitonic chalcogenides and dielectric insulators. Notably, the results show over 90% narrowband absorption in less than 4 nm active layer excitonic absorber medium at room temperature, along with enhanced photoluminescence in centimeter-scale samples. These superlattices exhibit strong light-matter coupling and exciton-polariton formation, paving the way for scalable, designer optical metamaterials.
