Abstract (en)
[origin: DE19824838A1] The invention relates to a device and method for growing crystals. According to the invention, signals which come from a neuronal network are superimposed on the control signals provided for a PID controller. Through this, single-crystals and polycrystals having a very high quality with regard to the outer shape and inner constitution are obtained.
