Abstract

Quantum dot Cellular Automata (QCA) is the emerging area in the field of nanotechnology. Inverter is a fundamental logic primitive in QCA. Molecular, semiconductor, magnetic, and metallic QCA are main methodology in the fabrication of quantum cell. While all types of QCA work on room temperature, metallic one is not suitable in normal temperature. So temperature plays a significant role in QCA circuit. In this paper, the effect of temperature in two-cell conventional inverter and recently proposed three-cell high polarized inverter has been discussed. The polarization and Kink energy of QCA circuit is influenced due to the change of distance between two cells. This paper clearly mentioned the variation of polarization and kink energy of QCA inverter due to cell displacement. Finally this paper makes a comparison between the conventional two-cell inverter and recently proposed three-cell inverter. The simulation tool QCADesigner has been used to study the effects of QCA
