摘要: 用動(dòng)態(tài)系統(tǒng)測(cè)量了-Si∶H靶電壓對(duì)光譜響應(yīng)的影響,發(fā)現(xiàn)對(duì)短波響應(yīng)影響較大。推導(dǎo)了靶光電流is和飽和電壓Vs的計(jì)算公式,發(fā)現(xiàn)Vs[(p,p)-1,2]。從測(cè)量的Vs值,計(jì)算了pp值。發(fā)現(xiàn)它隨入照光波長(zhǎng)的縮短而減小。估算了對(duì)單色光和對(duì)白光的最佳靶厚。

Abstract: The effect of the -Si:H target voltage on the spectral photosensitivity is measured in a demountable apparatus with interchangeable targets. It is found that the effect of target voltage on the photoresponse increases when the light wavelength decreases. The target photocurrent is and saturation voltage Vs are analysed. It is shown that Vs[(pp)-1, w2]. pp is calculated from measured Vs, value. It is found that pp value decreases when the light wavelength decreases. The optimal thicknesses of -Si:H targets for homogeneous light and achromatic light are estimated. -
