Modelling and Physical Implementation of Ambipolar Components Based on Organic Materials

conference paper

English

Systematic effort dedicated to the exploration of feasible ways how to permanently come up with even more space-efficient implementation of digital circuits based on conventional CMOS technology node may soon reach the ultimate point, which is mostly given by the constraints associated with physical scaling of fundamental electronic components. One of the possible ways how to mitigate this problem can be recognized in deployment of multifunctional circuit elements. In addition, the polymorphic electronics paradigm, with its considerable independence on a particular technology, opens a way how to fulfil this objective through the adoption of emerging semiconductor materials and advanced synthesis methods. In this paper, main attention is focused on various aspects standing behind the conception of polymorphic electronics together with a number of important benefits that can be obtained with the introduction of ambipolar elements. Besides that, relevant equivalent circuit models of the selected ambipolar components are presented in conjunction with the experimental results. However, key aspect depicting the novelty of the presented approach is primarily based on the hybrid combination of an initial chip infrastructure platform with the subsequent deposition of suitable organic semiconductor layer showing ambipolar property. Finally, the applicability for construction of real multifunctional circuits is clarified.
