Figure 2

Nanopatterns produced and imaged within a CH3(CH2)9S/Au(111) monolayer. (A) Thirty-two CH3(CH2)17SH molecules are grafted, forming a 2 × 4 nm2 “dot.” The “dot” is 8.8 Å higher than the surrounding monolayer, indicating that thiols are closely packed. (B) A 10 × 100 nm2 line of CF3(CF2)11(CH2)2SH molecules produced using NPRW. (C) Nanostructures with multiple components may be produced. Two small patterns of aldehyde terminated SAMs are grafted in a 600 × 600 nm2 square of CH3(CH2)17SH area. (D) Fabrication of arrays of nanostructures. Each element consists of CH3(CH2)17SH molecules. This array was engineered within 4 min.
