Abstract
The surface morphology of (001)-oriented single crystal MgO has been s tudied as a function of annealing temperature using atomic force micro scopy. The surface undergoes two significant changes in the temperatur e range 500 to 1750 degrees C. Following annealing at 1000 degrees C s urface facetting is visible with the formation of well-defined steps a nd terraces. Following annealing at temperatures greater than or equal to 1500 degrees C the faceted surface structure is lost and planariza tion of the surface occurs.
