EXPERIMENTAL-STUDY OF A FIELD-EFFECT TRANSISTOR USING ANTIGRANULOCYTES THIN-FILMS

We describe an experimental study of the electrostatic field effect in granular thin films. This effect is thought to be grounded on the intergrain junction property which is dual to the Josephson effect. In order to see the feasibility of the field effect transistor using this phenomena, we attempt to enhance the amplitude of the conductance modulation induced by the electric field. We examine the dependence of the field effect on the channel sheet resistance and on the channel dimension. The effect of trapped charge on the grains is also investigated. Considering the experimental results, we discuss the prospect of the granular thin film FETs.
