Gated Silicon Drift Detector Fabricated from a Low-Cost Silicon Wafer

Sensors, 2015
Inexpensive high-resolution silicon (Si) X-ray detectors are required for on-site surveys of traces of hazardous elements in food and soil by measuring the energies and counts of X-ray fluorescence photons radially emitted from these elements.

Detectors for the future of X-ray imaging

Radiation Protection Dosimetry, 2010
In recent decades, developments in detectors for X-ray imaging have improved dose efficiency. This has been accomplished with for example, structured scintillators such as columnar CsI, or with direct detectors where the X rays are converted to electric charge carriers in a semiconductor.
