Field effect on organic charge-ordered/Mott insulators

Electrostatic carrier injection into insulating molecular conductors has been examined by fabricating field effect transistor structure in two kinds of procedures. One procedure employed a direct growth of the organic single crystals by electrochemical reaction on platinum electrodes deposited on the gate dielectric. In the other procedure very thin crystals were laminated on the substrate in ethanol solution. We have succeeded in observing field effects in both methods and found that the lamination method gives better results. (C) 2008 Elsevier B.V. All rights reserved
