摘要
Space resolved Stark spectroscopy is introduced as a non invasive optical technique for imaging electrirfield distribution in organic semiconductors. Stark spectroscopy relies on the electric field induced change in the absorption/reflection. It is shown that local monitoring of Stark shift with confocal spatial resolution provides quantitative information on the strength of the local field as well as charge distribution within the transport channel.
