报告了微晶有限横向尺寸和厚度对典型物理吸附基质的结合能异质性影响的计算机研究结果。尺寸效应被证明会对结合能分布产生大尾部影响。对模型基底（100-Å 典型表面相干长度）的计算表明，20%-30% 的结合位点的能量与平均结合能相差大于 0.2%。然而，仅尺寸效应不足以解释真实基材的分布峰宽度。
Results of a computer investigation of the influence of crystallite finite lateral size and thickness upon the binding-energy heterogeneity of typical physisorption substrates are reported. Size effects are shown to contribute large tails to the binding-energy distribution. Calculations with the model substrate (100-Å typical surface coherence length) show that 20%-30% of the binding sites have energies which differ from the average binding energy by greater than 0.2%. Size effects alone, however, are insufficient to explain the distribution peak widths of real substrates.
