Abstract
An apparatus for forming a crystalline sheet. The apparatus may include a crystallizer comprising a first gas channel and a second gas channel, wherein the first gas channel and second gas channel extend through the crystallizer to a lower surface of the crystallizer between an upstream edge and a downstream edge. The first gas channel may be disposed closer to the downstream edge than the second gas channel. A first gas source may be coupled to the first gas channel, where the first gas source comprises helium or hydrogen, and a second gas source may be coupled to the second gas channel, where the second gas source does not contain hydrogen or helium.
