Method of manufacture of polymer transistors with controllable gap

A polymer transistor manufactured by a method comprising:

• positioning a conducting tip proximate to a conducting surface so as to form a gap;
• introducing an electrochemical medium in contact with the conducting tip and the conducting surface;
• applying an electrical potential across the electrochemical medium so as to deposit a conductive polymer that electrically bridges the gap so as to include the conducting tip as a part of the transistor;
• immersing the conductive polymer in an ionically conducting material;
• and
• providing a counter electrode adapted to perform as a transistor gate.

A method of manufacturing a plurality of conducting polymer transistors on a single conducting surface, the method comprising:

• positioning a plurality of conducting tips proximate to the conducting surface so as to form gaps between each of the plurality of conducting tips and the conducting surface;
• introducing an electrochemical medium in contact with the conducting tips and the conducting surface;
• and
• applying an electrical potential across the electrochemical medium so as to deposit a conductive polymer that electrically bridges the gaps so as to include the conducting tips as part of the transistors.
