    • Crystals are grown in ribbon shapes by an apparatus for supporting a film of source material, capacitive electrodes contacting the film and heat pipes in thermal contact with the electrodes for first heating the material through the electrodes to near its melting temperature and then for controllably cooling the electrodes, an rf heater using the electrodes for melting the film in a zone, a heat pipe for causing solidification along one surface of the melt zone to form a ribbon, a pulling mechanism for moving the ribbon from the melt zone, a heater for melting bulk replenishing material to replenish the melt, and an auxiliary heating device for heating the ribbon after leaving the zone to prevent dendritic growth by maintaining low axial temperature gradients.
    • 晶体通过用于支撑源材料的膜,与膜接触的电容电极和与电极热接触的热管的装置生长成带状,用于首先将材料通过电极加热至接近其熔融温度,然后可控地冷却 电极,使用用于熔化区域中的膜的电极的rf加热器,用于使熔融区域的一个表面固化以形成带状物的热管,用于使熔融区域移动的拉动机构,用于熔化的加热器 用于补充熔体的大量补充材料和用于在离开区域之后加热带的辅助加热装置,以通过保持低的轴向温度梯度来防止树突生长。
