Experimental evidence is given that the sublimation rate of vicinal silicon (001) surfaces depends on the misorientation. Three regimes are studied: step flow without and with Lochkeim-formation on the terraces, as well as the high temperature regime, where the surface becomes atomically rough. Qualitatively these observations are in agreement with theoretical predictions of the anisotropic KPZ-theory.
