英文摘要 | PURPOSE:To enhance the stability and the yield by a method wherein the title compound semiconductor single crystal epitaxial substrate is composed of four element mixed crystal in specific composition and almost equal composition ratios of III group elements in a well layer and a barreir layer. CONSTITUTION:Supposing that x3=0.29, y3=0.63 in the composition of a barrier layer 5 represented by an expression, the composition ratios x of III group elements and the composition ratios y of V group elements in the well layer 4 having the compressive strain of about 1% are respectively to be x2=x3=0.29, y2=0.85 while not only the composition ratios x of the III group elements are equalized but also the difference between the well layer 4 and the barrier layer 5 in the composition ratios y of the V group elements is lessened. On the other hand, the mixed crystallization i.e., the cause of the mutual diffusion of the constituent elements between the well layer 4 and the barrier layer 5 can be attributed to the difference in the composition ratios making the mixed crystallization hardly occur thereby enabling the yield of laser element and the longtime reliability to be enhanced. Furtheremore, the multiquantum well structure can be easily grown by a simple method due to the equalized composition ratios x of III group elements in the well layer 4 and the barrier layer 5. |
