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

Solution-grown organic semiconducting single crystals are robust and easy to handle materials that can reliably detect X-rays in the direct approach, operating at room temperature and in air, providing a linear response to increasing X-ray dose rates. We succeeded in realizing the fi rst thin and bendable X-ray direct detector based on organic semiconducting single crystals, signifi cantly enhancing its sensitivity and its minimum detectable dose rate.
