چکیده انگلیسی
The results of electrical characterisation and X-ray detection measurements of two different active area (0.06Â mm2 and 0.5Â mm2) commercial 4H-SiC Schottky photodiodes at room temperature are reported. The devices exhibited low dark currents (less than 10Â pA) even at a high electric field strengths (403Â kV/cm for 0.06Â mm2 diodes; 227Â kV/cm for 0.5Â mm2 diodes). The results of the X-ray measurements indicate that the diodes can be used as photon counting spectroscopic X-ray detectors with modest energy resolutions: FWHM at 5.9Â keV of 1.8Â keV and 3.3Â keV, for the 0.06Â mm2 and 0.5Â mm2 devices, respectively. Noise analysis of the photodiodes coupled to a custom low noise charge sensitive preamplifier is also presented.
