THz spectroscopy of emerging materials for light driven processes and energy harvesting

Abstract

Terahertz (THz) spectroscopy provides a crucial view on the electrical properties of emerging materials complementary to that which can be provided by more standard conductivity methods. The high frequency properties acquired in the THz range can be used to predict low frequency and DC behavior. THz spectroscopy provides insight into grain boundaries, phonon modes, and the underlying mechanism of charge transfer in general, paving the way towards superior design of novel materials. In this paper, we present pump-probe and time-domain THz spectroscopy on metal organic frameworks (MOFs) providing a detailed insight into carrier lifetime and charge scattering in MOFs.
