【摘要】 研究了长波ＨｇＣｄＴｅ光导探测器液氮温度电阻和室温电阻比值计算问题。结果表明：制成器件后，表面电导、材料电导率的变化和背景辐射都将使器件液氮温度的电阻减小，进行这三项修正后，器件电阻比值的计算值与实验值吻合更多还原

【Abstract】 The ratio of LWIR HgCdTe photoconductive detector resistance at room and liquid-nitrogen temperatures is calculated The result shows that the surface conduction,material conductivity changes,and background radiation have influence on the detector resistance at liquid-nitrogen temperature Calculation dataa grees with experimental results after having taken into account of these factors更多还原
