影响PbS红外接收元件极化及稳定的因素很多。我们于1979年上半年用正交实验法进行实验所得初步结果表明,硫化铅薄膜上下双层电极,经适当的清洁处理和干燥步骤,加之适当的光电负荷,可以减轻元件“极化”程度,并促其性能稳定。实验方法硫化铅元件是通过化学沉淀和敏化法制作的多晶薄膜。表面积大于体积。因此,工艺中的表面清洁度,电极接触等都会引起极化。我 There are many factors that affect the polarization and stability of the PbS infrared receiving element. Preliminary results from experiments conducted by orthogonal experiment in the first half of 1979 show that the upper and lower double layer electrodes of lead sulfide film can reduce the degree of “polarization” of the components by appropriate cleaning and drying steps, and proper photoelectric load, And promote its stable performance. Experimental Methods Lead sulfides are polycrystalline thin films made by chemical precipitation and sensitization. Surface area is greater than volume. Therefore, the process of surface cleanliness, electrode contact will cause polarization. I
