Electric field emission

Electric field emission is a phenomenon where electrons are released from a material when it is exposed to a strong electric field. Think of it as a powerful force that pulls the negatively charged electrons away from the atoms of a substance, causing them to escape into the surrounding space. This process is crucial in various technologies, including electron microscopy and vacuum tubes, where the controlled emission of electrons is necessary. It’s similar to how a strong gust of wind can dislodge leaves from a tree, allowing them to float away.
