ABSTRACT

Fullerene nanowhiskers (FNWs) are thin crystalline fibers composed of fullerene molecules, including C60, C70, endohedral, or functionalized fullerenes. FNWs display n-type semiconducting behavior and are used in a diverse range of applications, including field-effect transistors, solar cells, chemical sensors, and photocatalysts. Alkali metal-doped C60 (fullerene) nanowhiskers (C60NWs) exhibit superconducting behavior. Potassium-doped C60NWs have realized the highest superconducting volume fraction of the alkali metal-doped C60 crystals and display a high critical current density (Jc) under a high magnetic field of 50 kOe. The growth control of FNWs is important for their success in practical applications. This paper reviews recent FNWs research focusing on their mechanical, electrical and superconducting properties and growth mechanisms in the liquid–liquid interfacial precipitation method.

Mentions: A model describing the changes in the liquid–liquid interface upon manual mixing is shown in figure 3. The initial layered interface (figure 3(a)) is assumed to form a sinusoidally modulated interface (figure 3(b)) upon the manual mixing. The amplitude of this interface increases along the height of the glass bottle, a section of this wavefront is highlighted by the blue rectangle (figure 3(c)). This highlighted section is modeled by a cylinder with height h, radius r, basal area S, and volume V (figure 4(a)). The front of the liquid–liquid interface travels vertically with a velocity v.
