Silicon carbide crystals of the hexagonal type were grown in a kroll-type furnace by the sublimation technique. Both homogeneous and grown juncion rystals were prepared. A new krolltype furnace was constructed. Preliminary runs were made yielding crystals of high purity. The growth of junction crytals has emphasized the preparation of crystals with a high degree of perfection. The methods and materials of rectifier fabrication are being studied. MBIENT EFFECTS AND ELECTRICAL CHARACTERISTICS OF RECTIFIERS ARE GIVEN. (uthor)
