WebDec 20, 2024 · Growth time depends on the material, set temperature, flow rate and the desired crystal morphology. To achieve robust bulky rubrene crystals (good for discrete free-standing devices) we grow rubrene at 310 oC for about 48 h (the load size is ~ 300 mg). Growth procedure (Finishing the growth): 1. WebCzochralski growth, or crystal pulling, is the dominant commercial process for the growth of single crystals of silicon, compound semiconductors, metals, oxides, and halides. The Czochralski technique essentially consists of a crucible containing the material to be crystallized surrounded by a heater to melt the charge.
