AFM topography images of V2O5 nanowires and SWNTs on various SAM patterns. (A) V2O5 nanowires on uniform patterns comprised of ODT (bright area) and cysteamine (dark area). (B) V2O5 nanowires on the mixed SAM regions with gradient cysteamine surface molecular density on Au (ODT is utilized for passivation). (C) SWNTs on uniform cysteamine SAM patterns on Au. (D) SWNTs on gradient cysteamine patterns on Au. Theses patterns cover a large surface area (∼1 cm × 1 cm) on the substrates. (Reprinted with permission from Reference [207].
