    摘要: Nitride semiconductor wafers which are produced by epitaxially grown nitride films on a foreign undersubstrate in vapor phase have strong inner stress due to misfit between the nitride and the undersubstrate material. A GaN wafer which has made by piling GaN films upon a GaAs undersubstrate in vapor phase and eliminating the GaAs undersubstrate bends upward due to the inner stress owing to the misfit of lattice constants between GaN and GaAs.

    摘要: A method of producing a GaN crystal is directed to growing a GaN crystal on a GaN seed crystal substrate. The method includes the steps of preparing a GaN seed crystal substrate including a first dopant such that the thermal expansion coefficient of the GaN seed crystal substrate becomes greater than that of the GaN crystal, and growing the GaN crystal to a thickness of at least 1 mm on the GaN seed crystal substrate. Accordingly, there can be provided a method of producing a GaN crystal that can suppress generation of a crack and grow a thick GaN crystal, and a GaN crystal substrate.
