Abstract In this paper, a mesa-type 256×8 long-wavelength infrared detector is prepared by using InAs/GaSb type-II superlattice material with double barrieres structure. the area of each pixel is 25×25 μm2. The cut-off wavelength and dark current density of the detector at -0.05 V bias with liquid nitrogen temperature is 11.5 μm and 4.1×10-4 A/cm2, respectively. The power spectrum of low-frequency noise (1/f noise) at different temperatures have also been fitted by the Hooge model, and the correlations with dark current are extracted subsequently. The results shown that the 1/f noise of the detector is mainly caused by the generation-recombination current at a low reverse bias, however, when the reverse bias is high, the 1/f noise should be expressed by the sum of Igr noise and Ibtb noise which is ignored in the previous research. The 1/f noise-current correlation assessed in this work can provide insights into the low frequency noise characteristics of long-wavelength T2SL InAs/GaSb detectors, and allow for a better understanding of the main source of low-frequency noise.

Abstract The paper reports on the photoelectrical performance of the long wavelength infrared (LWIR) HgCdTe high operating temperature (HOT) detector. The detector structure was simulated with commercially available software APSYS by Crosslight Inc. taking into account SRH, Auger and tunnelling currents. A detailed analysis of the detector performance such as dark current, detectivity, time response as a function of device architecture and applied bias is performed, pointing out optimal working conditions.
