“…Moreover, the combination of high sensitivity and spatial resolution suggests the possibility of reading nanoscale electric memory cells entirely contact and current free. Finally, we stress that the molecular QD realization of SQDM reported here, although particularly attractive, does not exhaust all possibilities [32]. SQDM probes with nano-fabricated QDs on standard silicon AFM cantilevers may in the future extend the applicability beyond ultrahigh vacuum and cryogenic temperatures.…”

We introduce a scanning probe technique that enables three-dimensional imaging of local electrostatic potential fields with subnanometer resolution. Registering single electron charging events of a molecular quantum dot attached to the tip of an atomic force microscope operated at 5 K, equipped with a qPlus tuning fork, we image the quadrupole field of a single molecule. To demonstrate quantitative measurements, we investigate the dipole field of a single metal adatom adsorbed on a metal surface. We show that because of its high sensitivity the technique can probe electrostatic potentials at large distances from their sources, which should allow for the imaging of samples with increased surface roughness.

Lesson: Scanning Probe Microscopy: "feeling" what you can't see at the nanometer scale Standards:HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.HS-PS2-1. Analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
