Feasibility study of a SiC sandwich neutron spectrometer

The Fabrication and Characterization of Ni/4H-SiC Schottky Diode Radiation Detectors with a Sensitive Area of up to 4 cm2

“…Many other semiconductors have been used to fabricate detectors at the same time: CdTe, CdZnTe, GaAs, and AlInP are focused on photon detection [ 4 , 5 , 6 ]; diamond is suitable for neutron, photon, and charged particle detection and has ultra-high radiation resistance but with tiny dimension, uneven quality, and high cost [ 7 , 8 ]. By now, SiC detectors have been demonstrated to have a high resolution in the detection of charged particles [ 9 , 10 , 11 , 12 , 13 , 14 ], photons [ 15 , 16 , 17 , 18 ], and neutrons [ 19 , 20 , 21 , 22 ]. Particularly, because of their outstanding operations in applications in intense radiation fields and harsh environments, such as alpha particle monitoring and neutron detection in actinide waste-tank environments [ 23 ] and neutron and gamma-ray monitoring of spent nuclear fuel assemblies [ 24 , 25 ], and because the technology has matured in terms of material growth and device fabrication, they have been considered preferable substitutions for conventional silicon radiation detectors.…”

Study of radiation detection properties of GaN pn diode

“…[1][2][3][4][5] Furthermore, semiconductor materials have recently been proposed as new neutron detector materials. The following semiconductor materials have been studied as possible radiation detectors: Si, [6][7][8] CdTe, [9][10][11][12][13] CdZnTe (CZT), 14) SiC, 15) TlBr, [16][17][18][19] BN, 20,21) and GaN. [22][23][24][25] However, these semiconductor detectors are almost all γ-ray detectors and have not been studied for neutron detection.…”
