  "term": "Shot noise",
  "field": "Chemistry",
  "definition": "A type of electronic noise that arises from the discrete nature of charge carriers, such as electrons or photons, when they cross a potential barrier or are emitted randomly. In polymer science, it is relevant in the context of electron beam lithography, where the statistical fluctuations in the number of electrons arriving at a specific point contribute to image noise. This noise follows Poisson statistics.",
