摘要
6H-SiC ingots with diameters of 25-35 mm with flat natural surfaces have been grown by the Modified Lely method. Influence of the growth conditions and crucible geometry on the growth front shape and on the enlargement of the seeds have been investigated. The developed growth process allows the growth of ingots under quasi-equilibrium conditions with and without enlargement at a growth rate between 1-1.5 mm h(-1). (C) 1999 Elsevier Science S.A.
