Observation of surface roughening on Ni(115)

Abstract
We present evidence that the equilibrium topography of the Ni(115) surface in the temperature range 100 K<Tm) surfaces of face centered cubic (fcc) metals and is estimated that the roughening temperature of Ni(115) is below 50 K, that of Ni(113) approximately 200±50 K, and that of Ni(001) well above 420 K.
