Abstract
An electronic device includes a ferroelectric layer arranged on a channel region and a gate electrode arranged on the ferroelectric layer. The ferroelectric layer includes a plurality of first oxide monolayers and a second oxide monolayers that is arranged between the substrate and the gate electrode and include a material different from a material of the first oxide monolayers. The first oxide monolayers include oxide monolayers that are alternately formed and include materials different from one another.
