摘要

Diamond-like carbon (DLC) films were deposited by electrodeposition technique onto SnO_2-coated glass substrates by using a mixture of acetic acid and water as electrolyte at a fixed applied voltage 2.14 V. The films showed two distinct broad Raman characteristic peaks located at ~1365 cm~(-1) (D-line) and 1575 cm~(-1) (C-line). Band gaps of the films varied between 1.98 and 2.35 eV. Hydrophobicity in these films was studied by measuring the contact angles of water droplets and it was found that the films were extremely hydrophobic. The results were interpreted in terms of hybridization of carbon in these DLC films.
