Provided is a semiconductor device with negative differential transconductance. The semiconductor device includes a substrate, a gate electrode formed on the substrate, an insulating layer formed on the gate electrode, a source electrode material layer formed on the insulating layer, a semiconductor material layer formed on the insulating layer to be hetero-joined to the source electrode material layer, a source electrode formed on the source electrode material layer, and a drain electrode formed on the semiconductor material layer. A work function of the source electrode material layer is controlled by a gate voltage applied through the gate electrode, and the source electrode material layer shows negative differential transconductance depending on a level of the gate voltage.
