摘要: Signal-to-noise ratio (SNR) is a valuable figure of merit in determining the operating scope infrared detectors. Antenna-couple metal-oxide-metal diodes have been shown to detect radiation without cooling or applied bias, but so far hampered by their SNR. This paper details comprehensive study fabrication parameters that control formation tunneling oxide barrier optimize performance these Since affects both current-voltage and detection characteristics, can be optimized improve device performance. The characteristics devices are detailed this paper; resistance, nonlinearity, curvature coefficient parameterized on procedures. Infrared SNR studied as function nonlinearity biasing conditions.
