The application of nanotechnology in electronic components is referred to as nanoelectronics. The size of these components is often only a few nanometers. The smaller electronic components become, the more difficult they are to manufacture. Nanoelectronics comprises a broad spectrum of materials and devices with the common characteristic that they are so small that physical effects alter the materials ‘properties on a nanoscale. Inter-atomic interactions and quantum mechanical properties play a significant role in the workings of these devices.
Nanophotonics, sometimes known as nano-optics, is a branch of nanotechnology that studies light's behavior at nanoscale sizes and the interactions of nanometer-sized objects with light. Nanophotonics is a branch of nanotechnology, comprising the branch of electrical engineering, optics, and optical engineering. Controlling the properties of quantum emitters and improving their functionality requires nanophotonic devices.
