Single‐Molecule Devices
In article number 2202135, Zong‐Liang Li, Christian A. Nijhuis, Enrique Del Barco, and co‐workers report a single‐electron logic calculator formed by a gated Au/S‐(CH2)3‐Fc‐(CH2)9‐S/Au transistor. The unique adjacent conductive molecular orbitals in the Fc moiety are controlled by the orthogonal bias and gate voltages, resulting in the implementation of all universal logic...
Controllable single‐molecule logic operations will enable development of reliable ultra‐minimalistic circuit elements for high‐density computing but require stable currents from multiple orthogonal inputs in molecular junctions. Utilizing the two unique adjacent conductive molecular orbitals (MOs) of gated Au/S‐(CH2)3‐Fc‐(CH2)9‐S/Au (Fc = ferrocene) single‐electron transistors (≈2 nm), a stable single‐electron...
