We found that oxidation after forming the films greatly improved the performance of c _ ( 60 ) diodes . the diodes that were modified evidently excelled those that were not modified in rectification ratio in the same conditions 通過對氧化步驟的研究發(fā)現(xiàn):在相同條件下,經(jīng)過氧化的c _ ( 60 )二極管的開關比明顯高于未經(jīng)氧化的c _ ( 60 )二極管。
