1. A method for growing a nitride single crystal comprising steps of:
preparing a silicon substrate having a surface in (111) crystal orientation;
forming a first nitride buffer layer on the surface of the silicon substrate;
forming an amorphous oxide film on the first nitride buffer layer;
forming a second nitride buffer layer on the amorphous oxide film; and
forming the nitride single crystal on the second nitride buffer layer,
wherein the amorphous oxide film is an Al2O3 amorphous film and the first buffer layer comprises AlN.
