Many of the most sensitive X-ray detectors are based on toxic elements such as lead, limiting their safe applications. Here, the authors report the realization of sensitive X-ray detectors based on solution-grown thick BiI/BiI3/BiI van der Waals heterostructures, showing a detection limit down to 34 nGy s−1 and high stability.
