Atomic Force Microscopy of Liquid-Covered Surfaces: Atomic Resolution Images.

reportActive / Technical Report | Accession Number: ADA182482 | Open PDF

Abstract:

Images of graphite surfaces that are covered with oil reveal hexagonal rings of carbon atoms. Images of a sodium chloride, surface, protected from moisture by oil, exhibit a mono-atomic step. Together, these images demonstrate the potential of Atomic Force Microscopy AFM for studying both conducting and non-conducting surfaces - even surfaces covered with liquids. Our AFM uses a cross of double wires with an attached diamond stylus as a force sensor. The force constant is approximately 40 Nm. The resonant frequency is approximately 3 kHz. The lateral and vertical resolutions are 0.15 and 5 pm.
