Phonon-polariton Based THz Spectroscopy

Not Accessible

Your library or personal account may give you access


We demonstrate a THz spectrometer based on grating interferometric measurement of phonon-polariton propagation before and after interaction with a sample. The temperature dependent dielectric response of the relaxor ferroelectric KTN was measured.
