Abstract
An epitaxially coated silicon wafer comprises a plane surface misoriented relative to a {110} crystal plane, wherein the <110> direction of the single silicon crystal is tilted away by the angle θ from the normal to the wafer surface and the projection of the tilted <110> direction forms an angle φ with the direction <−110> in the wafer, and θ is given by 0≦θ≦3° and 45°≦φ≦90°, as well as for all symmetrically equivalent directions.
