摘要:
Homogeneously doped Si monocrystals of the n-type are produced from p- or n-type Si crystals having a random dopant concentration in radial and axial directions of the crystal and the dopant concentration within such crystals is adjusted by subjecting such crystals to controlled thermal neutron radiation.
