| Research Abstract |
Preparation of an AlN double buffer layer (DBL) on a β-Si_3N_4 layer by the interfacial reaction between Al and the β-Si_3N_4 layer was developed by controlling two electrical discharge modes of the high frequency induction coupling electrical discharge in molecular-beam epitaxy (MBE) method. Activity modulation migration enhanced (AM-MEE) method was established as a continuous MBE method by preparing the AlN/β-Si3N4/Si DBL layer firstly. In addition, the prospect to the growth of thermodynamically metastable cubic crystals, AlN and GaN epitaxial films on Si substrates was able to be obtained by the AM-MEE method.
