 Is there a value of property dark current in the following infrared text: 
 
 In this paper, p + -bilayer graphene (BLG)/n-Hg0.7783Cd0.2217Te heterojunction based long wavelength 
 infrared (LWIR: 2-12 µm) photodetector is reported.;The LWIR radiations are absorbed in 
 lightly doped n-Hg0.7783Cd0.2217Te active layer.;The drift-diffusion approach is used for 
 the simulation of the device.;Different recombination mechanism models such as Shockley-Read-Hall,
 Auger, and optical are considered for computing dark current.;The photodetector exhibits 
 dark current of 3.5 pA, photocurrent of 1.9 nA, and Iph/Idark ratio of 543 at -1 V bias.;
 The maximum external quantum efficiency (QEext) of 88.38%, 
 photocurrent responsivity of 4.5 AW -1 , specific detectivity (D * ) of 1.8×10 15 cmHz 1/2 W -1 , 
 noise equivalent power (NEP) of 3.53×10 -19 W, 
 and the 3-dB bandwidth of about 64.8 GHz at -0.5 V is achieved at 77 K, 
 confirms the suitability of proposed photodetector for low noise applications. Avoid using the following keywords: read, heterojunction, efficiency, text
