Atomic manipulation switches

We aim to employ single molecules or metal-molecule complexes as switches for novel concepts in information technology with ultimate scaling.

We discovered and characterized reversible switches based on hydrogen tautomerization [1], bond formation between a metal atom and a molecule [2], cyclization in radicals (reversible Bergman reaction, switching of the spin multiplicity) [3] and switching atomic charge states [4] and adsorption geometries [5].
