Imec News, Solid State Technology: At this week’s IISW (Snowbird, US, June 12-16 2013), imec and Holst Centre present a large-area fully-organic photodetector array fabricated on a flexible substrate. The imager is sensitive in the wavelength range between 500 and 600 nm, making it compatible with typical scintillators and therefore suitable for x-ray imaging applications.
Because of their very high absorption coefficient, organic semiconductors allow extremely thin active layers (10 to 50 nm). Also, given their low processing temperature, they can be processed on foils. As a result, organic imagers can be more robust and light-weight compared to their traditional counterparts and may be used for conformal coating of randomly shaped substrates. Moreover, the wide variety of organic molecules available ensures that the properties of the active layer can be tuned to applications requiring specific wavelength ranges.
