kind of magnetic circuit part that works similar to a resistor using a memory, initially imagined by American physicist Leon Chua almost four a long time before (in 1971).
The molten silicon freezes little by little onto the seed that has a crystalline structure that is certainly continual Along with the composition with the seed. The seed is slowly but surely withdrawn, generally when rotating, under cautiously controlled circumstances, and it delivers with it a cylindrical ingot of silicon That may be a single crystal throughout. This ingot may be nearly 300 mm (12 inches) in diameter and weigh approximately 100 kg (220 lbs .). (
