Abstract
Zinc phosphide (Zn${}_{3}\mathrm{P}_{2}$) is a promising earth-abundant material for solar cell applications but calls for the further understanding of its optoelectronic properties. In this work, we perform contact-free and noninvasive optical-pump terahertz probe (OPTP) spectroscopy on various Zn${}_{3}\mathrm{P}_{2}$ thin film samples and extract the crucial material properties – carrier lifetime and mobility-that dominate the electron transport and device performance, from the OPTP THz radiation response.
