- 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 was reached. Studies of radiation damage produced by 14 MeV neutrons, 19 MeV protons and 17 keV X-rays were performed and the resulting current increase, impurity removal and charge collection deficiency investigated. Long term storage and short term heat treatments showed appreciable annealing effects by up to 83%. In addition, we establish a testing system that can measure the soil salinization. Finally, we describe the reflection characteristics of visible, infrared and microwave in soil, which can be gotten by combining the spectrogram with the TM data.
