According to the rules of quantum mechanics, electrons behave as particles or waves. Similar to the walls of a water reservoir, “electrostatic potential walls” can be created to confine electrons to desired spatial regions, known to physicists as “quantum corrals.” Confining electrons allows physicists to work with them, the experimental counterpart to “particle in a box” exercises in undergraduate-level quantum mechanics.
