X-ray pixels including double photoconductors and x-ray detectors including the x-ray pixels

摘要

Example embodiments are directed to X-ray detectors including double photoconductors. According to example embodiments, the X-ray detector includes a first photoconductor on which X-rays are incident, and a second photoconductor on which X-rays transmitted through the first photoconductor are incident. The first photoconductor and the second photoconductor include a tandem structure. The first photoconductor is formed of silicon and absorbs X-rays in a low energy band, and the second photoconductor is formed of a material that absorbs X-rays in an energy band higher than the low energy band of the X-rays absorbed by silicon.
