Fig. 6From: Ultra-Thin Pyrocarbon Films as a Versatile Coating MaterialA 30-nm-thick PCF can be transferred, e.g., a on a pin hole with 300 μm diameter or b on a grating structure without supporting polymer layer. Also with 1-kV extra high tension (EHT), the film is nontransparent, but when EHT is increased to 5 kV, the film becomes semitransparentBack to article page
