Seminar DCSY - Šimek V.: Multifunctional Logic Circuits based on Advanced Nanoscale Materials

Initial purpose of this presentation is to clarify the rationale behind the need to find an alternative path how to properly address at least some of the most crucial shortcomings of CMOS-based conventional digital circuits. Main attention will be given to the possible ways how to extend the traditional abstraction of simple switching elements (i.e. transistors) by means of adopting the nanoscale materials likes silicon nanowires (Si-NWs), carbon nanotubes, graphene nanoribbons, organic polymers and other emerging structures and materials.

One of the key aspects in this perspective is the controllable ambipolar operation of such post-silicon devices, or at least some of them. This feature basically unlocks the possibility to prepare an efficient realization of contemporary digital circuits and also introduce an alternative path based on the adoption of multifunctional circuitry paradigm. Finally, the expected direction of research activities, which should finaly result into dissertation thesis, will discussed along with some of the achieved results.
