Abstract

<abstract abstract-type="normal"> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>The Debye temperature of wurtzite aluminum nitride (AlN) was determined by the Rietveld refinement method based on the room-temperature X-ray powder diffraction data. The refined lattice parameters are <italic>a</italic> = 3.11139(1) Å, <italic>c</italic> = 4.978 43(3) Å; the refined positional parameter for N is <italic>z</italic> = 0.384 59(33) Å; and the refined temperature factors of Al and N were 0.442(12) Ų and 0.559(33) Ų, respectively. Using this refined temperature factor, the Debye temperature was evaluated as 971 K through the Debye approximation.</p> </abstract>
