Thin film transistor and method of fabricating the same

An array substrate including a thin film transistor, comprising:

• a multi-coaxial silicon nanowire unit including a plurality of coaxial silicon nanowires on a substrate, the multi-coaxial silicon nanowire unit including a central portion and end portions of the central portion;
• a fixing layer on the central portion of the multi-coaxial silicon nanowire unit and the substrate, wherein the fixing layer secures the multi-coaxial silicon nanowire unit to the substrate;
• a gate electrode on fixing layer;
• a first source electrode and a first drain electrode on the respective end portions so as to electrically connect to the multi-coaxial silicon nanowire unit;
• a second source electrode connected to the first source electrode and a second drain electrode connected to the first drain electrode;
• and
• a pixel electrode connected to the second drain electrode.
