Figure 6

Representative current traces showing blinks that correspond to the formation of single-molecule junctions of 1,8-nonadiyne molecules on Si (a) and gold (b) substrates. The x axis does not represent a continuous acquisition time and time-breaks between each blink are added to account for this. A vertical offset has been applied to the baseline near to zero-current to display the single-molecule junction component only (tunnelling background subtracted). The applied surface-voltage biases are −0.8 and −0.2 V for Si and Au substrates, respectively, causing a current level for both type of junctions to be 3 nA. The initial set-point current was 1 nA in both cases.
