Abstract
The low-temperature heat-capacity data of small single crystals of sapphire obtained by an ac calorimetric technique are reported here. The lattice heat-capacity coefficient β is calculated to be 0.00172 mJ/g atom K4, giving a Debye temperature ϑD of 1042 K. This is in very good agreement with the published ϑD of 1035 K, on samples which were ∼1000 times larger.This publication has 3 references indexed in Scilit:
