H. Wiechert et al., DEUTERIUM MONOLAYERS PHYSISORBED ON KRYPTON-PLATED GRAPHITE - A 2-DIMENSIONAL ISING SYSTEM, Physica. B, Condensed matter, 234, 1997, pp. 164-166
Neutron-diffraction measurements were used for the first time to inves
tigate the influence of the modification of the graphite substrate pot
ential and of the substrate symmetry caused by a preadsorbed layer of
krypton (Kr). It will be shown that D-2 on Kr/graphite presents a new
2D Ising system. The order-disorder transition of this system has been
studied.
