STM imaging of 2D crystals

The following measurements show images taken with easyScan STM on 2-dimensional molecular crystals of dotriacontan and octadecanol molecular layers prepared on HOPG.

13x13nm image; z-range 2nm

Instructions on the properties of such crystals and how to prepare them can be found in "J.P. Rabe, S. Buchholz, Commensurability and Mobility in Two-Dimensional Molecular Patterns on Graphite, Science 253 (1991) 424-427"
