Paper Abstract
We present a comprehensive study of ultrafast time-resolved photconductivity in pentacene and functionalized pentacene single crystals and thin films measured using optical pump-terahertz probe technique. By investigating the wavelength and temperature dependence of the transient photoconductivity, we reveal a sub-picosecond wavelength-independent charge carrier photogeneration and band-like charge transport in both single crystal and thin film samples. The amplitude and decay dynamics of the photoconductivity transients are correleated with the morphology of the films, assessed by atomic force and electron microscopy.
