Abstract: PROBLEM TO BE SOLVED: To make it possible to have a large-band discontinuous value between semiconductor layers and to achieve lattice matching by using AlGaN for a barrier layer and using AlGaNbN for an active layer. SOLUTION: On an LiAlO2 substrate 1, an N-type GaN contact layer 2, an N-type Al0.2 Ga0.8 N barrier layer 3, an I-type Al0.1 Ga0.88 Nb0.02 N active layer 4 and a P-type GaN contact layer 6 are sequentially grown. Cleavage is performed by using the cleavage property to the LiAlO2 substrate 1 from the laminated structure formed in this way, and a laser element is manufactured. At this time, the band gap and the lattice constant of a P-type Al0.2 Ga0.8 N barrier layer 5 are set at about 3.87eV and 3.17Å, respectively. In the meantime, the lattice constant of an Al0.1 Ga0.88 Nb0.02 N active layer 4 is 3.169Å and approximately achieves the lattice matching with the P-type Al0.2 Ga0.8 N barrier layer 5. The band gap is set at about 2.8eV, and the large bandgap difference is obtained.
