From: Controlled Growth of Rubrene Nanowires by Eutectic Melt Crystallization

(a–d) Rubrene nanowires grown on the hydrophobically modified substrates. SEM micrographs of RB-NWBA prepared by (a) eutectic melt crystallization, and (b) EMAN. The minimum feature size of the RB-NWBA pattern was 80 nm. SEM micrographs of RB-NWSA prepared by (c) eutectic melt crystallization, and (d) EMAN. (e–f) RB-NWBA grown on hydrophilically modified substrate. Unlike RB-NWBA grown on the hydrophobically modified substrates, RB-NWBA grew vertically on the hydrophillically modified sustrate.
