GaN 晶体在 1165 °C 和 600 Torr 的专用电阻加热反应器中生长。在这种方法中,通过GaN粉末的分解获得气态镓,同时通过氨的离解提供氮气。通过使用这种稳定的 Ga 源,GaN 的生长速度超过 200 µm/hr。使用这种方法生长的 GaN 单晶通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、二次离子质谱 (SIMS) 和辉光放电质谱 (GDMS) 进行了广泛的表征。 (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA,魏因海姆)
GaN crystals were grown in a dedicated, resistively heated reactor at 1165 °C and 600 Torr. In this approach, gaseous gallium was obtained by the decomposition of GaN powder while nitrogen was provided from the dissociation of ammonia. GaN was grown at a rate of exceeding 200 µm/hr by using this stable Ga source. GaN single crystals grown using this method were extensively characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Secondary Ion Mass Spectrometry (SIMS), and Glow Discharge Mass Spectrometry (GDMS).
