Abstract

The dominant terahertz emission mechanism of highly doped silicon was determined by applying an external magnetic field of 0.65 T parallel to the surface of the sample. It was found via time-domain terahertz spectroscopy that with +0.65 and -0.65 T, a 14.49% increase and -3.71% decrease in terahertz emission was observed with almost no phase shift. Highly doped Si has a dominant surface field mechanism.
