Atomic Force Microscopy
The 'AFM' instrument is a Digital Instruments Nanoscope IV scanning probe microscope. It is equipped with 'E' and 'J' type scanners that are capable of scanning 15 × 15 micron and 200 × 200 micron areas respectively. The standard tip holder assembly may be used for tapping mode AFM, contact mode AFM and lateral force microscopy. These have been used for a wide variety of surface topography and surface friction measurements. We also have a fluid cell for examining samples under wet environments, which has been applied to study lipid layers adsorbed on mica substrates. Other options include a high speed scanning head, sample temperature control system and STM attachment.
