The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 21 2 2021 08 23 Optimization of infrared detector HgCdTe in photoconductive‏ ‏in the spectral region 2-6 µm‎ ‎ Optimization of infrared detector HgCdTe in photoconductive‏ ‏in the spectral region 2-6 µm‎ ‎ 401 407 1704 10.47176/ijpr.21.2.39191 FA Sh Mahmoody ‎‎ ‎ Department of Physics, Payame Noor University of Tehran, Tehran, Iran M Akoundi ‎‎ ‎ Department of Physics, Payame Noor University of Tehran, Tehran, Iran A Shokri; ‎‎ ‎ Department of Physics, Payame Noor University of Tehran, Tehran, Iran Journal Article 2019 10 05 In this paper a new method in design and modeling of infrared detector HgCdTe in photoconductive mode ‎is presented. In this method after scrutiny mechanical, optical, electrical properties of semiconductor ‎HgCdTe and solving the photoconductive equations, software of equations is programmed and with initial ‎value and repeat cycle, their changes to key parameters such as thickness, wavelength and amount of ‎impurities are calculated and finally, performance of detector is optimized.‎ Modeling of photoconductive detector has been done in temperature of 300K and 2-6 µm wavelength range‎‎, according to obtained results, optimal specific detectivity  is 3×10⁹ cmHz^1/2W^-1‎‏ ‏in 5.77 µm wavelength.‎ <br />  In this paper a new method in design and modeling of infrared detector HgCdTe in photoconductive mode ‎is presented.
