چکیده
Solar-blind metal–semiconductor–metal (MSM) photodiodes based on MOCVD-grown Al0.6Ga0.4N template have been fabricated and tested. AlGaN detector samples were fabricated using a microwave compatible fabrication process. Optical transmission, current–voltage, spectral responsivity, and temporal pulse response measurements were carried out. The fabricated devices had very low leakage current and displayed true solar-blind response with 255 nm cutoff wavelength.

The photodiode samples exhibited low leakage with dark current densities below 1 × 10 A/cm at 40 V reverse bias. Photoconductive gain-assisted photoresponse w...
متن کاملSolar-Blind Photodetectors for Harsh Electronics
We demonstrate solar-blind photodetectors (PDs) by employing AlN thin films on Si(100) substrates with excellent temperature tolerance and radiation hardness. Even at a bias higher than 200 V the AlN PDs on Si show a dark current as low as ~ 1 nA. The working temperature is up to 300°C and the radiation tolerance is up to 10(13) cm(-2) of 2-MeV proton fluences for AlN metal-semiconductor-metal ...
متن کاملDemonstration of the First 4H-SiC Metal-Semiconductor-Metal Ultraviolet Photodetector
Abstract. This paper demonstrates the first 4H-SiC metal-semiconductor-metal (MSM) UV photodetector. Two types of MSM photodetectors are fabricated for comparison: one in p-type 4HSiC and the other in n-type 4H-SiC. The n-type SiC photodetectors show a low dark current less than 10nA at -15V bias while the p-type ones show a lower dark current of 0.3nA at -25V. Photoresponsivity is measured fro...

The low-noise solar-blind photodetectors of indium-tin-oxide/LaAlO(3)/Ag (ITO/LAO/Ag) have been fabricated based on the properties of LAO bandgap excitation and the transparent conductance of ITO thin film. The ITO thin films are epitaxially grown on LAO wafers as the electrodes and detection windows of the photodetectors. The photodetectors have low noise and excellent electromagnetic shieldin...
