This paper describes experiments on three forms of temperature dependent surface behaviour. We use scanning tunnelling microscopy to investigate the diffusive motion of steps and kinks on two low-index crystal surfaces, Au(110) and Pb(111), and to directly observe the surface roughening transition on the vicinal Ag(115)surface. The high depth sensitivity of medium-energy ion scattering is exploited in the study of surface melting and the related high temperature faceting of surfaces vicinal to Pb(111).
