STM observation of steps and terraces on tungsten (2 1 1) surface

Thermally cleaned W(2 1 1) surface with 0.7° miscut consists of (2 1 1) terraces separated by monoatomic steps. When the surface is exposed to oxygen and subsequently annealed at 1100–1900 K, the width of (2 1 1) terraces increases and multilayer steps are formed. Similar step bunching is observed d...
