Measurement of dispersive forces between evaporated metal surfaces in the range below 100nm
Measurement of dispersive forces between evaporated metal surfaces in the range below 100nm
In this work, we describe dispersion force (van der Waals/Casimir) measurements between gold surfaces at separations as close as 12nm. The force measurements were performed in the plane-sphere configuration by atomic force microscopy at distances ranging between 12 and 200nm. This was accomplished by using evaporated smooth metal surfaces for …
