Abstract

A tunneling transistor includes a gate, an insulating layer placed on the gate, a carbon nanotube being semiconducting, a film-like structure, a source electrode, and a drain electrode. The carbon nanotube is placed on a surface of the insulating layer away from the gate. The film-like structure covers a portion of the carbon nanotube, and the film-like structure is a molybdenum disulfide film or a tungsten disulfide film. The source electrode is electrically connected to the film-like structure. The drain electrode is electrically connected to the carbon nanotube.
