Abstract :
We report on efficient terahertz electroluminescence from SiC structures with the natural superlattice. The emission spectrum demonstrates a single line, the maximum of which shifts linearly with increase in bias field. We attribute this emission to steady-state Bloch oscillations of electrons in SiC natural superlattice.
