THE TRANSITION FROM LOCALIZED TO MOBILE ADSORPTION

W DeMarcus,Jamie Dyer-1954-12-01

TL;DRAbstract

The mobility of nn isolated atom adsorbed on a crystalline surface is investigated using the laws of quantum mechanics. The results are in essential agreement with the customary rate equations when the particles are heavy or the potential barriers on the surface are high. The thermal properties of an adsorbed phase are also deduced on the assumption of low surface coverage. It is found that the specific heat curve is not a good indicator of mobility. (auth)
