Research Abstract |
Recently, we determined that mixed-valence copper coordination polymers including a dithiocarbamate ligand and bromide or iodide anions exhibited semiconducting properties with relatively high carrier mobilities, and we have attempted to apply the coordination polymers to the semiconducting materials of field-effect transistors (FETs). In this research, we found that a FET device with a ferroelectric coordination polymer CuBrBu2D performed at extremely lower voltage than those of the conventional organic FETs. The carrier mobility estimated from the output characteristics was found to be 30.1 cm2/Vs, which was higher than that of amorphous silicon. In addition, this FET shows ambipolar FET characteristics in the measurements of the transfer characteristics.
