(2025). The Effects of High-Energy Carbon Co-Doping on IMB-CNM LGAD Fabrication and Performance. Sensors, 25 (17), 5571.https://doi.org/10.3390/s25175571.1424-8220https://hdl.handle.net/11441/176954Over the past few years, Low-Gain Avalanche Detectors (LGADs) have demonstrated excellent timing performance, showing great potential for use in 4D tracking of high-energy charged particles. Carbon co-doping is a key factor for enhancing LGAD performance, which are detectors with intrinsic amplification, in harsh radiation environments. This work presents a broad pre-irradiation characterization of the latest carbon-co-implanted (or carbonated) LGADs fabricated at IMB-CNM. The results indicate that the addition of carbon reduces the nominal gain of the devices compared with non-carbonated detectors. Furthermore, a comprehensive study is presented on how carbon co-implantation can either enhance or suppress the diffusion of the multiplication layer during LGAD fabrication, depending on the device structure and fabrication parameters.application/pdf16 p.engAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/LGADX-rays and charged-particle detectorsalpha spectrometrydopant diffusion in siliconinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.3390/s25175571
