Abstract: An optical sensor includes a light-emitter device formed in a body of solid-state material with wide band gap having a surface. The light-emitter device includes a cathode region having a first conductivity type and an anode region having a second conductivity type. The anode region extends into the cathode region from the surface of the body. The anode region and the cathode region define a junction, and the cathode region has, near the junction, a peak defectiveness area accommodating vacancies in the crystalline structure due to non-bound ions or atoms of Group IV or VIII of the periodic table, which may include carbon, silicon, helium, argon, or neon. The vacancies are at a higher concentration with respect to mean values of vacancies in the anode region and in the cathode region. For example, the vacancies in the peak defectiveness area have a concentration of at least 1013 atoms/cm−3.

Abstract: An integrated electronic device for detecting the composition of ultraviolet radiation includes a cathode region formed by a semiconductor material with a first type of conductivity. A first anode region and a second anode region are laterally staggered with respect to one another and are set in contact with the cathode region. The cathode region and the first anode region form a first sensor. The cathode region and the second anode region form a second sensor. In a spectral range formed by the UVA band and by the UVB band, the first and second sensors have, respectively, a first spectral responsivity and a second spectral responsivity different from one another.

Abstract: A semiconductor device for a system for measuring temperature, which includes a first UV detector and a second UV detector. The first and second UV detectors generate a first current and a second current, respectively, as a function of the irradiance in the ultraviolet band. Moreover, the first and second UV detectors have coefficients of variation of the current with temperature, at constant irradiance, that are different from one another.
