Operating principles and performance of a novel a-Si H p-i-n-based X-ray detector for medical image applications.

Operating principles and performance of a novel a-Si H p-i-n-based X-ray detector for medical image applications.

This work develops a novel hydrogenated amorphous silicon (a-Si:H) p-i-n photodiode-based X-ray detector aimed at medical image applications. The new detector consists of an a-Si:H p-i-n photodiode and a stacked dielectric layer, deposited on the p-layer (n-i-p-SiNx) or the n-layer (p-i-n-SiNx) of t...
