A smoothing method for semiconductor material and semiconductor wafers produced by the method are disclosed. Semiconductor wafers with reduced atomic steps, as well with reduced scratches and subsurface defects can be produced. Such wafers feature an improved growth surface that can provide for the growth of an epilayer with reduced macroscopic defects and defect densities. A method of smoothing the surface of a wafer according to example embodiments of the invention includes planarizing the surface of a semiconductor wafer, and then oxidizing the wafer to achieve a specified thickness of oxide on the surface of the wafer. The oxide can then be stripped from the surface of the semiconductor wafer.
