As the demand for miniaturization of electronic devices is largely consumer-driven, factors such as low cost and massive market applications are important. Conducting polymers are being used to replace both conventional metals and inorganic materials in a variety of applications, especially in microelectronic devices. To be effectively applied in microelectronic devices, the conducting polymers must be easily fabricated into micro- to nanoscale patterns. However, the construction of conducting polymer based microelectronic devices has been impeded by the technical challenges, mainly due to the intractability of conducting polymers. Here, we show a new way for the production of 3-dimensional structures of conducting polymers at the nanometer scale through regioselective nucleation of conducting polymers using the thin films of block copolymer. Our method mimics natural systems in which structurally organized surfaces of block copolymer films catalytically or epitaxially induce the regioselective nucleation and growth of specifically oriented inorganic and organic structures. Since our approach is quite simple and works for a large number of metals and polymers, sophisticated nanosized electronic devices such as nanosized transistors can be simply formed from their respective precursors. |
