Silicon detector for the Saline Soil Degree in ETM Image
A silicon photoconductor apparatus having improved efficiency in infrared radiation detection by sandblasting the reflective surface of the apparatus and thereby creating a near-infinite number of reflecting angles and a corresponding multiplication of quantum energy yield.This article describes its architecture,including its design,implementation,and performance.The novel method,a combination of surface barrier and planar processes,has resulted in detectors with excellent quality and long term operation stability.A current density of down to 1nA/cm2 wu reached.Studies of radiation damage produced by 14 MeV neutrons,19 MeV protons and 17 keV X-rays were performedand the resulting current increase,impurity removal and charge collection deficiency investigated.Long term storageand short term heat treatments showed appreciable annealingeffects by up to 83%.
