This article applies the two-mode vibronic model to study the dimeric molecular mixed-valence cell for quantum cellular automata, considering various exchange interactions and vibrational modes. The results demonstrate the potential for combining molecular QCA function with spin switching in electronic devices, aiding the rational design of multifunctional molecular electronic devices.
In this article, we apply the two-mode vibronic model to the study of the dimeric molecular mixed-valence cell for quantum cellular automata. As such, we consider a multielectron mixed valence binuclear d2-d1-type cluster, in which the double exchange, as well as the Heisenberg-Dirac-Van Vleck exchange interactions are operative, and also the local (breathing) and intercenter vibrational modes are taken into account. The calculations of spin-vibronic energy spectra and the cell-cell-response function are carried out using quantum-mechanical two-mode vibronic approach based on the numerical solution of the dynamic vibronic problem. The obtained results demonstrate a possibility of combining the function of molecular QCA with that of spin switching in one electronic device and are expected to be useful from the point of view of the rational design of such multifunctional molecular electronic devices.
