Ab initio studies of counterion effects in molecular quantum‐dot cellular automata

open access: yesJournal of Computational Chemistry, Volume 45, Issue 7, Page 392-404, March 15, 2024.
Randomly‐placed external counterions near ionic computational molecules may degrade QCA device operation. Ab initio calculations show that presence of nearby counterions affect the electron transfer (ET) matrix element and the inner‐sphere reorganization energy of a molecule.
