摘要
Results of the study of the terahertz electroluminescence from 8H-, 6H- and 4H-SiC natural superlattices (NSL) under action of strong electrical field applied along the natural superlattice axis are reported. It is shown that the threshold field of the appearance of THz BO emission and the threshold field for the negative differential conductivity for these SiC NSLs increase linearly with the width of the first miniband of these NSLs. This observation is a crucial factor in support of the BO nature of the terahertz electroluminescence and the negative differential conductivity for these SiC NSLs.
