David J.P.R. 37461740800 7401645580 57189468185 25647614700 Avalanche photodiodes; Characterization; Diodes; Infrared imaging; Leakage currents; Nitrides; Photodiodes; Photonics; Silica; Silicon nitride; Thermography (imaging); B-staged bisbenzocyclobutene; Current-voltage characterization; InAs; Low noise; Surface leakage currents; Surface passivation; Passivation The effect of surface passivation on the etched-mesa InAs diodes was investigated by carrying out the fabrication and passivation of InAs diodes. Extensive and detailed current-voltage characterization was done to determine the most suitable type of insulating material for the surface passivation. SU-8, silicon nitride, silicon dioxide and B-staged Bisbenzocyclobutene were used for the purpose of minimizing the conductivity of the etched mesa surface of InAs diodes. The forward- and reverse-biased characteristics of InAs diodes were measured at room temperature and 77 K in order to carefully investigate the effect of different surface passivation schemes. The results of this work categorically indicated that SU-8 is the most effective surface passivation material for InAs diodes, whereas silicon nitride and silicon dioxide have contributed to an even higher surface leakage current. Furthermore, SU-8 passivated InAs diodes were more sustainable to high bias voltages and its robustness increases the opportunity of its utilization for practical applications such as infrared imaging. � 2016 IEEE.
