Abstract
The thermal conductivities of LaAlO3 and NdAlO3 have been measured for the first time between 10 and 300 K. These substrates can be classified as intermediate thermal conductors. The measured room temperature values of 9 W m−1 K−1 for LaAlO3 and 7.5 W m−1 K−1 for NdAlO3 are close to those predicted from the crystal structure of these materials, despite the fact that the crystals are twinned.
