“Engineering Nanostructured Materials for Advanced Lithography, Optoelectronics, and Beyond”
Nanomaterials have attracted attention due to their immense potential in modern nanoscale optoelectronics, photonic and plasmonic devices. With the rapid progress in the system requirements, driven in part by Moore’s law, the demand for lower dimension and cost effectiveness has also increased. Among several approaches to achieve this goal, block copolymers (BCPs) have received considerable attention due to the inherent self-assembly property which can lead to various nanoscopic structures, such as spheres, cylinders, bicontinuous gyroids, and lamellae, depending on the composition and chain architecture of the BCPs. The resulting sizes of the microdomains can range from ~5-50 nm. In this talk, I will present self-assembled BCPs thin films assisted patterning approach for sub-20 nm inorganic nanomaterials. I will also talk about potential applications of these patterned nanostructures in perovskite solar cells and metamaterials
