A secondary electron arises as a result of the interaction of a primary electron with a specimen. In principle the term refers to all electrons emitted from a specimen after it has been bombarded with primary electrons, X-rays or other radiation. In practice the phrase most commonly refers to low-energy electrons (kinetic energy less than 50eV) emitted from the specimen in a scanning electron microscope (SEM).
