Abstract: An apparatus for sensing radiation is provided. Certain examples provide an apparatus including: a first layer including a sensor, wherein the sensor is configured to be responsive to changes in an electric field in the vicinity of the sensor; a second layer including a substrate configured to produce charge carriers in response to incident radiation; and a third layer including a plurality of electrodes, wherein the plurality of electrodes are configured to be selectively addressed during a readout operation of the sensor. Certain examples, relate to an apparatus for sensing X-rays or sensing neutrons including a graphene field effect transistor.
