Oscillations of the crystal–melt interface caused by harmonic oscillations of the pulling rate for the cylindrical phase of crystal growth
M. G. Vasil'ev Ioffe Institute, St. Petersburg
Abstract:
A technique for measuring the crystal cross-sectional area with a weight sensor based on the difference between its readings at the extreme rod positions in the stepwise and continuous modes of modulation of the pulling rate is proposed for the low-thermal gradient Czochralski method. A change in the crystallization rate at harmonic oscillations of the pulling rate is estimated with the aim of conserving the quality of the growing crystal for this measurement method.
