Stochastic Processes in CHEMFETs

Abstract

The fluctuation analysis has been extended to study of liquid/liquid interface and of phospholipid bilayer membranes. These studies were done with a discrete amplifier as opposed to FETs used before. This technique allows to carry out impedance measurements approximately one decade below that normally used in AC impedance analysis. The representation of power spectra on logarithmic scale of frequencies without distortion has been developed. This is a new approach to digital filtering. Preliminary investigation of chemical modulation of work function of synthetic metals has been initiated. It has been shown that a rigorous control of electropolymerization conditions can produce materials of widely different work function.
