Abstract

Self-assembled monolayers of 4-thiobiphenyl and 2-thiophenanthrene molecules on Au {111} were probed using scanning tunneling microscopy (STM) to investigate their assembled order, to measure the conductance through them, and to determine what molecular features are necessary for molecules to exhibit conductance switching. The 4- thiobiphenyl molecules assemble into two distinct packing structures, whereas no order is ...
