Stochastic Processes in CHEMFETs

Abstract

It has been shown that equilibrium fluctuation analysis offers a fundamentally different approach to characterizations of dynamic properties of various electrochemical systems ranging from fast redox couples, to liquid/ liquid interface, bilayer membranes and even insulator/solution interface. These measurements can be extended to frequencies approximately one decade below those normally used in AC impedance analysis . The representation of power spectra on logarithmic scale of frequencies without distortion has been developed. Chemical modulation of work function has been identified as an important factor which has to be considered in application of materials such as synthetic metals. Our preliminary study shows that a rigorous control of electropolymerization conditions can produce materials of widely different work function.
