Filling this gap is important because integrated circuits have shrunk so far that their active regions, which rely so heavily on silicon and germanium, begin to resemble ornate molecules rather than extended solids. Here we unveil a new approach for synthesizing atomically discrete wires of germanium and present the first conductance measurements of molecular germanium using a scanning tunneling microscope-based break-junction (STM-BJ) technique. Our findings show that germanium and silicon wires are nearly identical in conductivity at the molecular scale, and that both are much more conductive than aliphatic carbon. We demonstrate that the strong donor ability of C–Ge σ-bonds can be used to raise the energy of the anchor lone pair and increase conductance. Furthermore, the oligogermane wires behave as conductance switches that function through stereoelectronic logic. These devices can be trained to operate with a higher switching factor by repeatedly compressing and elongating the molecular junction.","lang":"eng"}],"pmid":1,"page":"12400-12405","day":"16","external_id":{"pmid":["26373928"]},"date_created":"2024-09-09T09:43:25Z","date_updated":"2024-12-18T11:24:37Z","year":"2015","extern":"1","publication":"Journal of the American Chemical Society","date_published":"2015-09-16T00:00:00Z","_id":"17968","citation":{"short":"T.A.
