<p>Single crystal composed of silicon with a section having a diameter that remains constant, are pulled by a method wherein the single crystal is pulled with a predefined pulling rate vp having the units [mm/min]; and the diameter of the single crystal in the section having a diameter that remains constant is regulated to the predefined diameter by regulating the heating power of a first heating source which supplies heat to the single crystal and to a region of the melt that adjoins the single crystal and is arranged above the melt, such that diameter fluctuations are corrected with a period duration T that is not longer than (2·18 mm)/vp.</p> |
