A Single-Molecule Digital Full Adder

A specifically designed aza-starphene molecule is presented where contacting one, two, and/or three single Al adatoms allows this to function as a “3-inputs & 2-outputs” digital full adder on Au(111) surface. Sequentially positioning with atomic precision interact aza-starphene, inputs one classical digit per Al, which converted quantum information by the molecule. The intramolecular logical calculations do not require solid-state cascade-like architecture. measured Boolean truth table results in part from level repulsion effect and nonlinear magnetic also intrinsic its contacted adatoms.
