  1. In czochralski silicon crystals ( czsi ) through fast neutron irradiation, formation and conversion of defects were investigated using fourier transform infrared spectroscopy ( ftir ), positron annihilation technology ( pat ) and scanning electron microscope ( sem ). the results showed that fast neutron irradiation induced large quantity of metastable defects which can be the capture centers of positron, positron annihilation average lifetime of samples increased with increasing of irradiation dosage. positron annihilation average lifetime of irradiation samples through dosage up to 1 1018 n. cm - 2 tended to constant

    本文對直拉硅樣品進行了不同劑量的快中子輻照,在硅中引入大量的亞穩態缺陷,研究這些亞穩態缺陷的形成,並在較寬的溫度范圍內對輻照樣品進行了退火處理,研究退火后亞穩態缺陷的轉化及同硅中氧的相互作用,應用傅立葉變換紅外光譜技術( ftir ) 、正電子湮沒技術( pat )和掃描電鏡( sem )進行了測試。
