“…Especially, the MPCVD growth technique has been widely used nowadays for the growth of large-size SCD [12,13] and led to numerous applications of diamond as a semiconductor material. These applications include field-effect transistors and diodes for power electronics [14][15][16][17][18][19][20], microwave devices [21][22][23][24][25], deep-ultraviolet (DUV) light emitting diodes (LED) [26][27][28], DUV photodetectors [29,30], radiation detectors [31][32][33][34][35], microelectromechanical systems (MEMS) [36][37][38][39], and quantum sensors [40][41][42]. The utilization of diamond as a heat sink has also been attracting growing interesting in the application of high-power high-frequency communication, electrical power switch and others, in which the thermal dissipation is a problem [43][44][45][46][47].…”

Diamond with an ultra-wide bandgap shows intrinsic performance that is extraordinarily superior to those of the currently available wide-bandgap semiconductors for deep-ultraviolet (DUV) photoelectronics and microelectromechanical systems (MeMs). the wide-bandgap energy of diamond offers the intrinsic advantage for solar-blind detection of DUV light. the recent progress in high-quality single-crystal diamond growth, doping, and devices design have led to the development of solar-blind DUV detectors satisfying the requirement of high Sensitivity, high Signal-to-Noise ratio, high spectral Selectivity, high Speed, and high Stability. On the other hand, the outstanding mechanical hardness, chemical inertness, and intrinsic low mechanical loss of diamond enable the development of MeMs sensors with boosted sensitivity and robustness. the micromachining technologies for diamond developed in these years have opened the avenue for the fabrication of high-quality single-crystal diamond mechanical resonators. in this review, we report on the recent progress in diamond DUV detectors and MeMs sensors, which includes the device principles, design, fabrication, micromachining of diamond, and devices physics. the potential applications of these sensors and a perspective are also described.

“…The available results indicate an upper operational limit of T < 240 • [126,128,[195][196][197][198][199][200][201][202], while a limit of about 300 • C for a 400 µm thick detector operated in pulse mode was reported in [199], and a claim of stable operation up to ~330 • C was reported in [126] for a diamond detector 100 µm thick. A recent paper [202] claims, for a detector 65 µm thick realized with tungstene metal contacts and irradiated by protons, a stable operation up to about 425 • C, the highest temperature reported so far for a diamond detector.…”

“…Studies of diamond detectors operating at HT date back to the beginning of the 2000s when the first artificial SCD films become available and are still ongoing [128,153,154,[195][196][197][198][199][200][201][202]202] reports on the irradiation at HT using protons. Usually, the detectors are studied while operating in pulse (spectrometric) mode, and PHS are recorded versus temperature to measure the variation of the detector performances (CCE, energy resolution at FWHM, peak centroid, and area).…”

Diamond is widely studied and used for the detection of direct and indirect ionizing particles because of its many physical and electrical outstanding properties, which make this material very attractive as a fast-response, high-radiation-hardness and low-noise radiation detector. Diamond detectors are suited for detecting almost all types of ionizing radiation (e.g., neutrons, ions, UV, and X-ray) and are used in a wide range of applications including ones requiring the capability to withstand harsh environments (e.g., high temperature, high radiation fluxes, or strong chemical conditions). After reviewing the basic properties of the diamond detector and its working principle detailing the physics aspects, the paper discusses the diamond as a neutron detector and reviews its performances in harsh environments.
