Abstract
Young's moduli of silicon single crystals were measured in the temperature range from room temperature to 1000 degrees C. The moduli were calculated f rom the resonance frequencies in the flexural mode of vibration. This metho d for measuring the moduli is thought to be more reliable than using the co nventional tensile tests. Young's mudulus in the temperature range from 800 degrees C to 1000 degrees C did not decrease as much as expected. The depe ndency on boron concentration was also investigated and found to be minimal in this temperature range and at boron concentrations of up to 8.5 x 10(18 ) atoms/cm(3).
