| Abstract: | 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 depthD and the gas-surface dispersion coefficientC
3). 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. |
