| The integration of molecular components with semiconductor platforms provides the basis for hybrid molecular semiconductor electronic devices. Towards this goal, we have examined the characteristics of various redox-active porphyrin monolayers attached to patterned Si (100) surfaces via a Si-C bond. The formation of monolayers on Si was confirmed by fast scan cyclic voltammetry. The electrochemical properties were investigated for both liquid and gel electrolytes. Gel electrolytes afford the advantage of solid-state packaging, which is necessary for real devices. Electrochemical impedance spectroscopy was used to measure the conductivity of gel electrolytes. The electron-transfer rates and charge retention characteristics of the memory cell were examined by swept waveform AC voltammetry and open circuit potential amperometry, respectively. |
