It is a photoconductor that is often the detector used as a flat-panel x-ray imager. It has a cost to manufacture and develop and easily scalable, but has low [[Electron Mobility|charge carrier mobility]], low charge conversion efficiency, high depth dependence, and has a high [[dark current]] when put into an electric field.
