Nanoscale electrocrystallization is a novel device fabrication process which is cost-effective, energy-saving, and eco-friendly. By this method, high-performance nanowires can be formed site-selectively with low power consumption, via electrolysis in solution. By electrolysis using an alternating current, nanowires can be fabricated only at the narrowest area between two electrodes. Hence, it is possible to fabricate a device structure such as a transistor, as the two electrodes are bridged by the nanowire. In other words, nanodevices can be fabricated by electrolysis in a test tube. Utilizing this technique, we prepared several nanocrystals and investigated their crystal structure and electronic properties. Furthermore, the magnetic or the electric field effect of the nanocrystal was also investigated to examine feasibility of electronic devices. An attempt of nanocrystal fabrication in an all-atmospheric process without using semiconductor process in the fabrication of electrode substrates was introduced. In this chapter, we review the fundamental technology of nanoscale electrocrystallization and focus on the site-selective fabrication of organic nanocrystals, with its application to electronic devices. The electrical characteristics of these devices are also discussed, followed by our perspective on nanofabrication.
