A Near-Infrared Enhanced Silicon Single-Photon Avalanche Diode with a Spherically Uniform Electric Field Peak
IEEE Electron Device Letters(2021)
摘要
A near-infrared (NIR) enhanced silicon single-photon avalanche diode (SPAD) fabricated in a customized $0.13~\mu \text{m}$ CMOS technology is presented. The SPAD has a depleted absorption volume of approximately $15\,\,\mu \text{m}\,\,\times 15\,\,\mu \text{m}\,\,\times 18\,\,\mu \text{m}$ . Electrons generated in the absorption region are efficiently transported by drift to a central active av...
