Abstract(in English) | AlN/GaN multilayer structure have relatively large refractive index differences in the group-III nitride semiconductors, which are expected to obtain high reflectivity distributed Bragg reflectors (DBRs) with a relatively small number of pairs. On the other hand, due to the cracks caused by the lattice mismatch, it is difficult to fabricate DBRs having high reflectivities in a large area. In this paper, we fabricated AlN/GaN DBRs on AlN templates for the first time in order to suppress the cracks by minimizing the tensile strain in the DBR layers. A high reflectivity of 97.5% was achieved in the 30 pair AlN/GaN DBR on AlN template. |
