Abstract

The thermal expansion of 6H Silicon Carbide with different dopant concentrations of aluminum and nitrogen was determined by lattice parameter measurements at temperatures from 300 K to 1575 K. All samples have a volume of at least 6 x 6 x 6 mm(3) to ensure that bulk properties are measured. The measurements were performed with a triple axis diffractometer with high energy x-rays with a photon energy of 60 keV. The values for the thermal expansion coefficients along the a- and c-direction, alpha(11) and alpha(33), are in the range of 3.10(-6) K(-1) for 300 K and 6.10(-6) K(-1) for 1550 K. At high temperatures the coefficients for aluminum doped samples are approximately 0.5.10(-6) K(-1) lower than for the nitrogen doped crystal. alpha(11) and alpha(33) appear to be isotropic.
