摘要: A method of changing the crystallographic orientation of a single crystal body is disclosed that includes the steps of characterizing a crystallographic orientation of the single crystal body and calculating a misorientation angle between a select crystallographic direction of the single crystal body and a projection of the crystallographic direction along a plane of a first exterior major surface of the single crystal body. The method further includes removing material from at least a portion of the first exterior major surface to change the misorientation angle.
