摘要: Abstract The heat of adsorption noble gas molecules A on metallic substrates B is described in terms the energy adhesion, generated at interface shared by adsorbed and substrate. adhesion (and hence adsorption) related to zero temperature surface energies γ0 two materials Δγ a d = −2Φ(γ 0 Aγ B) 1 2 . relation presented from which approximate constant Φ can be derived for arbitrary combinations metals Van der Waals crystals. Predictions gases are tabular form.
