Two-dimensional phase diagram of neon adsorbed on exfoliated graphite. Heat-capacity measurements

Heat-capacity measurements of neon adsorbed on bare Grafoil for coverages between 0.100 and 0.900 of a monolayer were made as a function of temperature in the range of 6.0 to 20.0 K using the quasiadiabatic method. From the data a two-dimensional phase diagram was constructed which indicates a triple-point temperature of 13.57 K and a critical-point temperature of about 15.8 K. Whenever possible our results are compared with the data obtained by other authors.
