Abstract
Many thermoelectric compounds possess terahertz (THz) phonon modes, which play a key role in improving the thermoelectric performance. To assess the THz phonon modes of thermoelectric materials, the present THz spectroscopy system requires a thin sample with a large area. We found that a compact THz spectroscopic chip can detect phonon absorption even for a small amount of a conductive sample. The chip would complement the conventional THz spectroscopy system, especially when a large crystal cannot be grown.
