Abstract AR
حضرت كواشف التوصيل الضوئي Ge-Au من بلورات مفردة من الجرمانيوم المطعم بتراكيز مختلفة من الذهب.
عين طيف الاستجابية Rλ و الكشفية النوعية D* كدالة للطول الموجي كذلك تم حساب الربح و الاستجابة الضوئية النسبية، المقاومة و التوصيلية في الظلام و عند الإضاءة بالإشعاع تحت الأحمر لتراكيز الذهب المختلفة.
لوحظ تحسن واضح في الاستجابة الضوئية و الربح للعينات ذات المقاومة الأعلى لكن على حساب قيم الكشفية النوعية.
Abstract EN
Ge-Au infrared photoconductive detection was prepared from germanium single crystal which were doped with different gold concentration using thermal evaporation.
The spectral resonsivity (Rλ), spectral detectivity (D*) were determined as function of wavelength, also the resistance, conductivity in dark and with illumination to infrared radiation, the gain and relative photo response have been measured with different gold concentration.
Remarkable improvements in the photoresponse gain were observed for the highest resistance specimen at the expense of spectral detectivity values.
