Pulling and Stretching a Molecular Wire to Tune its Conductance

open access: yes, 2015
A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured during the lifting procedure are associated to the detachment of molecular
