摘要：采用微波等离子体氮源合成了尺寸达50 μm的InN晶体。用x射线衍射对所制得的纤锌矿型InN粉末进行了表征。在100-673 K的温度范围内测量了晶格参数。在296（±3）K下，三种样品的平均室温晶格参数分别为a = 3.5374(1) a, c = 5.7027(5) a。计算密度为6.923±0.003g cm−3。研究温度范围内的热膨胀系数为a a = 3.6(2) × 10−6K−1和a c = 2.6(3) × 10−6K−1。
Abstract InN crystals of size up to 50 μm were synthesized using a microwave plasma source of nitrogen. The InN powder of wurtzite-type structure obtained was characterized by X-ray diffraction. Lattice parameters were measured in the temperature range 100–673 K. The average room-temperature lattice parameters of three of the samples studied at 296(±3)K are a = 3.5374(1)A, c = 5.7027(5)A. The calculated density is 6.923 ± 0.003g cm−3. The thermal expansion coefficients in the temperature range investigated are a a = 3.6(2) × 10−6K−1 and a c = 2.6(3) × 10−6K−1.
