Abstract

Dark current densities of 0.13 and 0.44pA/μm² at biases of 5 and 10V, respectively, have been obtained for InAlAs/InGaAs metal-semiconductor-metal photodetectors with a 2μm electrode width and spacing, by placing the electrode tips and contact pads on top of an insulating layer of silicon nitride. This is the lowest known dark current density reported for InAlAs/InGaAs metal-semiconductor-metal photodetectors to date.
