Multi-layer thin films are often the basis of photonic devices. Zinc oxide (ZnO) with its excellent optoelectronic properties can serve as a high quality emitter in structures like microdisks or photonic crystals. Here. we present a detailed study on the enhancement of the structural properties of low-temperature MBE grown ZnO on silica (SiO2). https://www.herbsdailyes.shop/product-category/popcorn/
