Abstract

Un sistema para formar pequeños cuerpos semiconductores de tamaño casi uniforme, con límites de grano mínimo, a partir de cuerpos de material semiconductor, que comprende: un tubo de alimentación para recibir dichos cuerpos; un susceptor térmico que circunda dicho tubo de alimentación y que rodea a una trayectoria de caída libre por debajo de dicho tubo de alimentación, un tubo que encierra dicho susceptor, y medios de calentamiento que circundan a dicho tubo para establecer un nivel de temperatura cerca de dicho tubo de alimentación situado por encima del punto de fusión de dicho material semiconductor y para establecer un gradiente de temperaturas predeterminado durante las siguientes partes inferiores de dicha trayectoria de caída libre, a una temperatura inferior a dicho punto de fusión.
