Growth and observation of micro-organic crystals in two-dimensional glass nanovolume cell

A simple type of glass cell to control the organic crystal growth in microsize by electrochemical method is presented. We fabricated growth cells with electrodes patterned by photolithograph and nanoliter volume. They have several merits for growth of organic conductors in microsize, including confined growth volume, observable growth space, rapid growth cycle relative to conventional methods, and compatibility with existing microfabrication techniques. The real time observation of the crystal growth was performed. The results are discussed in terms of the growth mechanism, suggesting a possibility of another microscopic view of crystal growth.
