Monolayer solids of short (perfluoro)alkanes on graphite

Calculations are reported for the relative stability of monolayer solid latices on graphite for C$_2$H$_6$, C$_3$H$_8$, C$_2$F$_6$, and C$_3$F$_8$. Triangular, centered rectangular and two-sublattice herringbone lattices are treated. The calculations use all-atom (AA) models and are based on non-bonding interactions formulated for three dimensional dense phases of alkanes and perfluoroalkanes.
