Claim Text:
1. An apparatus comprising: a heat source; a crucible disposed above the heat source and operative to contain molten silicon in which a top surface of the molten silicon is defined as a growth interface; an anisotropic thermal load leveling component disposed between the heat source and the crucible operative to even-out temperature and heat flux variations emanating from the heat source; a baffle structure extending from an interior wall of the crucible, the baffle structure having a top surface configured to be entirely submerged within the molten silicon and having a bottom surface disposed above a floor of the crucible; and a pump disposed within the crucible and oriented to direct a flow of the molten silicon over and along the top surface of the baffle structure in a first direction and under and along the bottom surface of the baffle structure in a second direction opposite the first direction.
