Sentence examples for sheath evolution from inspiring English sources
From the ion sheath evolution, it is also found that the sheath structure changes with time.
The fast sheath evolution brings a shortage of ions arriving at the deeper section of the trench.
The distributions of film thickness and implanted dose are studied, considering the current distribution inside the trench and the ion sheath evolution.
The ion sheath evolution inside the trench with a width of 30 mm and a depth of 20 mm is experimentally observed.
