pure silicon carbide radiation detector

Silicon - Wikipedia

Silicon tetrachloride is manufactured on a huge scale as a precursor to the production of pure silicon, silicon dioxide, and some silicon esters. [70] The silicon tetrahalides hydrolyse readily in water, unlike the carbon tetrahalides, again because of the larger size of the silicon atom rendering it more open to nucleophilic attack and the ability of the silicon atom to expand its octet which

5/12/2018· The properties of silicon (Si) and silicon carbide (4Н-SiC) detectors after their exposure to different integral fluxes of xenon (Xe) ions are presented. The detectors were irradiated at the IC-100 cyclotron of the Flerov Laboratory of Nuclear Reactions at the Joint Institute for Nuclear Research. It is shown that the degradation of the spectroscopy characteristics of a SiC detector occurs at
