Abstract:
1. A method for making a thin film transistor, the method comprising the steps of: (a) providing a growing substrate; (b) applying a catalyst layer on the growing substrate; (c) heating the growing substrate with the catalyst layer in a furnace with a protective gas therein, supplying a carbon source gas and a carrier gas at a ratio ranging from 100:1 to 100:10, and growing a carbon nanotube layer on the growing substrate; (d) forming a source electrode, a drain electrode, and a gate electrode; and (e) covering the carbon nanotube layer with an insulating layer, wherein the source electrode and the drain electrode are electrically connected to the single-walled carbon nanotube layer, the gate electrode is opposite to and electrically insulated from the single-walled carbon nanotube layer.
