We calculate the density of4 He at which a monolayer completes when adsorbed at zero temperature on a hypothetical substrate (characterized by the potential well depth D and the gas-surface dispersion coefficient C3). In the case of an alkali metal substrate, the monolayer is fluid; otherwise, it is a two-dimensional solid, except for H2, which is a borderline case. We discuss the prospects for monolayer superfluidity.
