We propose a process for easily fabricating a unique one-dimensional fullerene crystal, i.e., a fullerene finned-micropillar (FFMP). To fabricate a one-dimensional fullerene crystal more easily than when using current processes, fullerene was first annealed at 1173 K for 1 h with an argon gas flow of 0.5 L/min. We then examined how the FFMP structure changed when the fabrication process conditions, such as temperature, annealing time, and argon gas flow rate, were varied. FFMPs can be prepared within a short time and may have the same electrical characteristics as other one-dimensional crystals, e.g., fullerene nanowhiskers, so they are expected to be very useful for field-effect transistors, organic photovoltaics, and so on in the near future.
我们提出了一种可轻松制造独特的一维富勒烯晶体的方法，即富勒烯翅片微柱体（FFMP）。为了比使用当前方法更轻松地制造一维富勒烯晶体，首先在0.5 L/min的氩气流中于1173 K对富勒烯进行1小时退火。然后，我们研究了在诸如温度、退火时间和氩气流速等制造工艺条件变化时，FFMP结构是如何改变的。FFMP可在短时间内制备出来，并且可能具有与其他一维晶体（如富勒烯纳米须）相同的电学特性，因此预计在不久的将来它们对于场效应晶体管、有机光伏等将非常有用。
