Abstract :
3-inch Si doped GaAs crystals with low dislocation density (⩽100 cm-2) were developed by the Vertical Boat (VB) method. The shape of the solid/liquid interface was controlled by the temperature gradient near the interface. The desirable interface shape for low dislocation density was studied both empirically and through computer simulation. By improving the interface shape, the stable production of crystals with low dislocation density were achieved
