摘要：
本文通过比较未处理和等离子体处理样品的结构和输运性质，系统研究了氧等离子体暴露对属于钙钛矿家族Pr1-xSrxMnO3锰氧化物（x = 0.5）低带宽化合物的影响。研究发现，高温输运由小极化子承担，而低温输运归因于变程极化子。X射线衍射图谱的Rietveld分析表明，输运性质的变化可归因于等离子体暴露引起的结构修饰。此外，氧等离子体暴露由于在等离子体暴露样品中整合了氧离子而提高了电导率，从而使样品富氧。
英文摘要：
A methodical inquiry of the outcome of oxygen plasma exposure in low bandwidth compounds belonging to the perovskite family Pr1-xSrxMnO3 manganites where x = 0.5, has been presented in this communication by comparing the structural and transport properties of the untreated and plasma treated samples. It is witnessed that the high-temperature transmission is carried out by small polarons while the low-temperature transmission is attributed to variable range polarons. The changes in the transport properties may be attributed to the structural modification due to plasma exposure as revealed by the Rietveld analysis of the X-ray diffraction pattern. Further, oxygen plasma exposure boosts the conductivity due to the integration of oxygen ions in the plasma-exposed samples, thereby rendering them oxygen-rich.
