A poly(methyl methacrylate) blocking layer was found to reduce the dark current density in CH 3 NH PbI -based direct-conversion X-ray detectors as low 70 pA cm −2 .
Stabilized amorphous selenium (a-Se) photoconductive layers are currently used in the majority of modern digital x-ray flat panel imaging detectors mammography. We examine effects pre-exposure a-Se to high-dose irradiation on both hole and electron lifetimes, τe τh, respectively, without any field applied device. The was from an Al-filtered tungsten target tube. show that reduction τh depends only total or accumulated dose, D, absorbed a-Se, not rate dose delivery, dD/dt, over range 0.15...
