▎ 摘　　要

NOVELTY - The device (100) has a first electrode comprising fingers comprising nanotube material. A second electrode comprises second fingers with nanotube material, where the second fingers are interdigitated with the first fingers. A voltage source applies voltage across the first and second electrodes. A chamber (105) contains the first and second electrodes and gas (106), where a wall of a chamber enabling passage of radiation is external to the chamber. A voltage source and detection circuit (120) detects radiation within the chamber based on change in current across the first and second electrodes resulting from ionization of the gas by the radiation. The nanotube material is made of carbon nanotube material and graphene material. The gas is formed as inert gas that is krypton, nitrogen, argon, and xenon. USE - Device i.e. X-ray detector, for detecting radiation such as X-ray radiation and gamma radiation (all claimed). Uses included but are not limited to medical imaging, aerospace, defense, security applications, nuclear physics, high-energy physics, astrophysics, and radiochemistry. ADVANTAGE - The device has high detection efficiency, high energy resolution, room temperature operation, high sensitivity, low-cost, and lightweight, and can be fabricated in a large area in a simple and cost-effective manner with high mechanical flexibility. The device operates sensor devices with an extremely low voltage of 5 Microvolts to reduce power consumption of 40-45 femtowatt with high superb X-ray sensing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of detecting radiation. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a device for detecting radiation. 100Device for detecting radiation 105Chamber 106Gas 110Sensor 120Voltage source and detection circuit
