本文主要研究有机单晶p-n结纳米带的生长和输运性质。有机纳米电子学的发展要求有机纳米p-n结的制备成为高性能器件和集成电路的重要组成部分。在这里，我们证明了有机半导体的单晶p-n结纳米带的形成，通过选择性结晶的铜酞菁（铜酞菁，p型）单晶纳米带上的十六烷基或酞菁（F（16）CuPc，n型）。F（16）CuPc在CuPc上的结晶需要几个参数，包括相似的分子结构、相似的晶格常数和沿纳米取向轴的沿着π堆叠。在场效应晶体管中观察到p-n结纳米带的双极输运，F（16）CuPc和CuPc的平衡载流子迁移率分别为0.05和0.07 cm（2）V（-1）s（-1）。基本的p-n结纳米晶体管光伏器件在AM 1.5模拟光下显示出电流整流。这种离散的p-n结纳米带可以作为理解有机-有机界面上基本电荷传输和光伏行为的理想系统。
This article focuses on the growth and transport properties of organic single-crystalline p-n junction nanoribbons. The development of organic nanoelectronics requires the fabrication of organic nanometer-sized p-n junctions for high-performance devices and integrated circuits. Here we demonstrate the formation of single-crystalline p-n junction nanoribbons of organic semiconductors by selective crystallization of copper hexadecafluorophthalocyanine (F(16)CuPc, n-type) on copper phthalocyanine (CuPc, p-type) single-crystalline nanoribbons. The crystallization of F(16)CuPc onto CuPc requires several parameters, including similar molecular structures, similar lattice constants, and pi-stacking along the nanoribbon axis. Ambipolar transport of the p-n junction nanoribbons was observed in field-effect transistors with balanced carrier mobilities of 0.05 and 0.07 cm(2) V(-1) s(-1) for F(16)CuPc and CuPc, respectively. A basic p-n junction nanoribbon photovoltaic device showed current rectification under AM 1.5 simulated light. The discrete p-n junction nanoribbons may serve as ideal systems for understanding basic charge-transport and photovoltaic behaviors at organic-organic interfaces.
