Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To grasp the lamination limit, enhance the quality controllability, reduce the cost and expand the use, by a method wherein a crystal strain within the growth surface of the single crystal layer of the layer couple consisting of the buffer layer and the single crystal layer is made to transfer from a crystal strain within the growth surface of the single crystal layer of the layer couple deposited under the lower part of the single crystal layer of the above layer couple to the side of a compressive strain. SOLUTION: A GaN low-temperature deposited buffer layer 14 is grown on a sapphire substrate 12 and thereafter, a GaN single crystal layer 16 is grown on the layer 14. The above process is repeated for a desired number of times and layer couples consisting of the layers 14 and 16 are formed. Here, the grating constant of the C-axis of the uppermost layer GaN single crystal layer 16 is decreased less than that of a bulk material in the case where the number of the layer couples is two or more. According as the number of the layers couples is increased, the grating constant of the C-axis is decreased less than that of the bulk material. That is, in the case where the number of the layer couples is two or more, it is shown that a tensile strain is generated within the growth surfaces of the single crystal layers.
