FILM STRUCTURE, ELEMENT, AND MULTILEVEL ELEMENT

摘要

A film structure according to an embodiment of the present invention includes: at least one layer of an active monolayer having an energy level quantized in at least one direction; and at least one layer of a barrier alternately laminated with the at least one layer of the active monolayer, wherein a current flows in the active monolayer, and the flow of the current may be limited by the quantized energy level.
