The interaction of a gas molecule with a sensing material causes the highest change in the
electronic structure of the latter, when this material consists of only a few atoms. If the …

Recognition tunneling (RT) is an emerging technique for investigating single molecules in a
tunnel junction. We have previously demonstrated its capability of single molecule detection …

The electrical conductance of a series of thiol-terminated alkanes,(1, 6-hexanedithiol (HDT),
1, 8-octanedithiol (ODT), and 1, 10-decanedithol (DDT)) was measured using a modified …
