Toward Low-Voltage and Bendable X-Ray Direct Detectors Based on Organic Semiconducting Single Crystals

Organic materials have been mainly proposed as ionizing radiation detectors in the indirect conversion approach. The first thin and bendable X‐ray direct detectors are realized (directly converting X‐photons into an electric signal) based on organic semiconducting single crystals that possess enhanc...

Description
Summary:Organic materials have been mainly proposed as ionizing radiation detectors in the indirect conversion approach. The first thin and bendable X‐ray direct detectors are realized (directly converting X‐photons into an electric signal) based on organic semiconducting single crystals that possess enhanced sensitivity, low operating voltage (≈5 V), and a minimum detectable dose rate of 50 μGy s−1.
