Low‐Temperature Self‐Assembly of Novel Encapsulated Compound Nanowires

Nickel sulfide nanowires and compound‐filled MoS2 nanotubes have been grown by controlled annealing of patterned fullerene and nickel thin films on molybdenum substrates. The versatile synthesis route gives highly crystalline nanostructures at temperatures below 550 °C with a high degree of positional control. The Figure shows a portion of an as‐grown nickel sulfide nanowire 19 nm in diameter (scale bar 2 nm).
