Abstract
The formation of a new type of ordered 2D Ni3Al overlayer by low-temperature codeposition on NiAl(110) is demonstrated by kinetic Monte Carlo simulation of a multisite atomistic lattice-gas model with a precise treatment of surface diffusion kinetics. Simultaneous codeposition with 3∶1 Ni∶Al yields poor ordering at 300 K but well-ordered structures by ~500 K. Sequential codeposition of Ni
