Ordered silicon nanorod arrays with controllable geometry and robust hydrophobicity
Ordered silicon nanorod arrays with controllable geometry and robust hydrophobicity |
| Fig.#cod#x00A0;5. a Schematic of Cassie model. #cod#x03B8; * is the phenomenal contact angle. b Schematic of the top-down view of the nanorod arrays. The diameter of the nanorod is d and the lattice constant of the hexagonal lattice is a . The unit cell of the hexagonal lattice is chosen as the parallelogram. f s can be calculated as the ratio of the deep dark area to the unit cell area. |
