Secondary Electrons
Secondary electrons are electrons that are ejected from a material when it is struck by high-energy particles, such as photons or other electrons. When these high-energy impacts occur, they transfer enough energy to some of the material's outer-shell electrons, causing them to be released from the surface. This process is utilized in various technologies, including electron microscopes and cathode ray tubes, enhancing imaging and displaying capabilities. Secondary electrons play a crucial role in understanding material properties and behaviors at the microscopic level.

Secondary electrons are electrons that are emitted from a material after it is struck by high-energy particles, such as photons or primary electrons. When these primary particles collide with the material, they can transfer enough energy to dislodge some of the material's electrons. The released electrons, now referred to as secondary electrons, can create more ionization and contribute to various phenomena in physics and engineering, including in electron microscopy and semiconductor technologies. Their behavior is important for understanding material properties and interactions at the microscopic level.
