- 論文の詳細を見る
In a hydrogen plasma with a hot electron component the sheath voltage on the carbon surface has been observed to be extremely low compared with the theoretical prediction. It was identified that the yield of secondary electron emission from hydrogen absorbed carbon surface is 1.5 times as large as the value of pure carbon by comparing the experimental observations with the sheath theory and also by investigating a drastic increase of sheath voltage from 100V to 210V with an increase in the temperature of carbon surface from 380K to 900K when the temperature of hot electrons was kept constant at 100eV.
