16/8/1983· Silicon carbide crystals have also been produced by gaseous cracking in at least five vapor systems. It is produced primarily in batch type furnaces ranging up to 60 ft. long by 10 ft. wide and holding up to about 200,000 lbs. of sand-coke mix.
Structures and local electronic states of disloion loop …
The atomic- and electronic-level structures of a disloion loop and a stacking fault in 4H-SiC crystal are investigated by using large-scale tight-binding (TB) molecular-dynamics simulation. We employ a linear-scaling TB method implemented on a parallel computer in order to accelerate the 9,600-atoms calculation which is required for such a nanoscale simulation.
