Abstract
A method of manufacturing a polymer transistor having a controllable gap is provided in an embodiment. In the embodiment, a conducting tip is positioned proximate to a conducting surface so as to form a gap, an electrochemical medium is introduced in contact with the conducting tip and the conducting surface, and an electrical potential is applied across the electrochemical medium so as to deposit a conductive polymer that electrically bridges the formed gap. In another embodiment, a counter electrode is provided in the electrochemical solution, facilitating processing in which the electrochemical potential at the conducting tip and at the conducting surface are the same and there is a return path for electrical current through the counter electrode. Repositioning of the tip during and after polymer deposition provides, in a further embodiment, adds additional capability with respect to gap control and polymer properties.
