Summary

A low temperature atomic force microscope, based on the optical lever detection method and operated in liquid nitrogen vapour at ambient pressure, has been constructed. The experimenal results show that atomic resolution images can be obtained on both mica and highly oriented pyrolytic graphite at temperatures down to 79 K with sufficient thermal stability. In liquid nitrogen vapour, no surface contamination was observed after many hours of continuous operation, which demonstrates that such an approach is ideal for biological applications for its lower cost and easy maintenance.
