Abstract: | The paper reports on photoelectrical performance of the mid-wave infrared (MWIR) (111) HgCdTe high operating temperature detector for the fast response conditions. Detector structure was simulated with software APSYS by Crosslight Inc. The detailed analysis of the time response as a function of device architecture and applied voltage was performed pointing out optimal working conditions. The time response of the MWIR HgCdTe detector with 50 % cut-off wavelength of (lambda _{c} approx 5.3, upmu hbox {m}) at (T = 200) K was estimated at the level of (tau _{s} approx ) 2,500 ps for (V = 100) mV and series resistance (R_{Series} = 510,Omega ) . The series resistance’s reduction enables to reach (tau _{s}approx 60!-!500) ps. |
