AbstractThe performance of thermally evaporated pentacene TFTs is strongly affected by defects. The influence of the preparation conditions on the level of defects were studied by Photoconductivity (CPM) and Photothermal Deflection Spectroscopy (PDS). CPM and PDS are powerful tools to provide insights in the band structure, the sub band gap absorption, distribution of defects and the ordering of the material. The influence of the preparation conditions on the morphology and the structural properties will be discussed and correlated with experimental data of CPM and PDS. In particularly, the influence of the deposition temperature on the absorption spectra of the polycrystalline films will be addressed. Furthermore, the material analyse will be correlated with the device performance of pentacene TFTs.
