Patent attributes
Various techniques are provided to utilize nanostructures for process monitoring and feedback control. In one example, a method includes forming a layer of material including nanostructures distributed therein. Each nanostructure includes a quantum dot and a shell encompassing the quantum dot. The shells and quantum dots are configured to emit a first and second wavelength, respectively, in response to an excitation signal. The method further includes applying the excitation signal to at least a portion of the layer of material. The method further includes detecting an emitted signal from the portion of the layer of material, where the emitted signal is provided by at least a subset of the nanostructures in response to the excitation signal. The method further includes determining whether a manufacturing characteristic has been satisfied based at least on a wavelength of the emitted signal. Related systems and products are also provided.
