摘要：

The 3 omega method has been applied to measure the anisotropic thermal conductivity of single crystals of SiO2 (quartz) and La14-yCayCu24O41 (y = 9 and 10). A two-dimensional heat conduction model along with properly oriented metal heater strips have been employed to determine the in-plane and cross-plane thermal conductivity of these dielectric bulk oxides in the temperature range of 90-300 K. In addition, 3 omega measurements on a single crystal of SiO2 (0001) using heaters of different width (12 mu m and 32 mu m) resulted in the same thermal conductivity value.
