Deuterium monolayers physisorbed on krypton-plated graphite: A two-dimensional Ising system

Neutron-diffraction measurements were used for the first time to investigate the influence of the modification of the graphite substrate potential and of the susbrate 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...

Description
Summary:Neutron-diffraction measurements were used for the first time to investigate the influence of the modification of the graphite substrate potential and of the susbrate 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.
