The roughening temperature of the densest crystal face of Ar, Kr, CO and CH sub(4) derived from multilayer adsorption studies

Layering critical temperatures have been determined from adsorption isotherms for four systems (Ar on CdCl sub(2), Kr, CO or CH sub(4) on graphite) for coverages of up to 4 or 5 layers. An estimate of the roughening temperatures of the (111) faces of Ar, Kr and CH sub(4), and of the (1000) face of b...

Zusammenfassung:Layering critical temperatures have been determined from adsorption isotherms for four systems (Ar on CdCl sub(2), Kr, CO or CH sub(4) on graphite) for coverages of up to 4 or 5 layers. An estimate of the roughening temperatures of the (111) faces of Ar, Kr and CH sub(4), and of the (1000) face of beta -CO is derived from the results.
