摘要

In article number 1901108, Feng Huang, Jun Chen, and co‐workers design a direct conversion X‐ray detector based on a HgI2 crystal and a ZnO nanowire vacuum diode to overcome the current runaway effect at high operating electric field and improve the detection sensitivity. The detector shows a sensitivity of 6.8 × 103 μCGyair−1 cm−2 and a response time of 0.24 ms. The proposed X‐ray detector is promising for the application of low dose X‐ray detection.
