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