Integration of CdSe/ZnS Quantum Dots into As-induced Etched Nanovoids on GaSb
Quantum dots, due to their small size, portray unique optical properties that are different compared to those of the bulk material. The most apparent of these properties is the excitation of these dots, resulting in emission of photons, which are visible to the human eye as light. More …
