Terahertz time-domain spectroscopy technique for characterizing GaN thin film

Open Access Open Access


The indices of refraction, extinction constants and complex conductivities of the GaN film for frequencies ranging from 0.2 to 2.5 THz are obtained using THz time-domain spectroscopy. The results correspond well with the Kohlrausch stretched exponential model.
