X-ray pixels including double photoconductors and x-ray detectors including the x-ray pixels
First Claim
1. A pixel of an X-ray detector, the pixel comprising:
- a first photoconductor configured to generate electron-hole pairs in response to X-rays incident on the first photoconductor;
a first electrical circuit configured to detect at least one electron or hole generated by the first photoconductor and convert the electron or hole into a first electrical signal;
a second photoconductor on the first photoconductor, the second photoconductor configured to generate electron-hole pairs in response to X-rays transmitted through the first photoconductor; and
a second electrical circuit configured to detect at least one electron or hole generated by the second photoconductor and convert the electron or hole into a second electrical signal,wherein the X-rays incident on the first photoconductor are of a lower energy band compared to the X-rays incident on the second photoconductor.

Abstract
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.
