Abstract

Zinc phosphide ( Zn3P2) 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 Zn3P2 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.
