      abstract     = {This thesis has presented the creation and characterization
                      of a single molecule device. A new microscopy method, SQDM,
                      was developed and shown to be capable of measuring local
                      electrostatic potential in a truly quantitative fashion. The
                      nature of the single molecule sensor itself was investigated
                      in-depth and unexpected results were achieved, contradicting
                      the predictions of the highly successful orthodox theory of
                      the Coulomb blockade. The single molecule device was
                      constructed with the use of atomically precise single
                      molecule manipulation detailed in Chap. 2. Approaching the
                      microscope tip towards a single molecule, a covalent bond
                      was formed between the apex atom of the tip and one of the
                      double-bonded corner oxygen atoms of the molecule. This bond
                      was empirically found to be strong enough to remove the
                      molecule not only from its chemisorbed state on the surface,
                      but from its hydrogen-bonded molecular layer. The removals
                      were made possible by the augmentation of the SPM setup with
                      a three-dimensional motion tracking device, which was used
                      to explore custom removal trajectories by selective
                      variation. Since the molecule’s geometry was controlled
                      throughout the manipulation process, it was thereafter
                      possible to re-deposit the molecule to the surface by
                      re-approaching and applying a voltage pulse. Using this
                      protocol, the word ‘JÜLICH’ was patterned into a PTCDA
                      monolayer by removing molecules one by one. The correction
                      of a mistake in the patterning was also demonstrated by
                      lowering a molecule into a previously created vacancy.
                      Currently work is underway to further the understanding of
                      the key parameters involved in successful removal
                      trajectories. Next, the functionality of the single molecule
                      device was exhibited in Chap. 3 with the development of
                      SQDM. It was shown that the molecular QD was sufficiently
                      electronically decoupled from the tip’s electronic states
                      that integer charge could be stabilized on it: the presence
                      of resonant tunnelling features as well as sudden changes in
                      the tip-sample force were the signals of single electron
                      charging. The [...]},
