Multi-scaled evaluation for self-organized carbon nanotube electron emitters

控制碳纳米管（CNTs）的自组织形貌是将其应用于场发射（FE）型发光元件的电子发射体的目的。为了形成具有有效电子源所需的中等间距和数密度的CNT发射器，系统地研究了从自组织CNT发射器到宏观器件特性的FE特性。通过多尺度评价、碳纳米管生长的控制和器件结构的优化，极大地改善了满足其FE性能的制备条件。预期所获得的发现适用于各种常规基板所容许的工艺。

Control of self-organized morphologies of carbon nanotubes (CNTs) was aimed to apply them for electron emitters in field emission (FE) type light emitting elements. In order to form CNT emitters with moderate spacing and number density desirable for an efficient electron source, FE properties ranging from self-organized CNT emitters to macroscopic device properties were systematically studied. Through the multi-scaled evaluation ; control of CNT growth and optimization of device structures, the preparation condition to fulfill their FE properties was highly improved. It is expected that the findings obtained are applied for the processes tolerable for a variety of conventional substrates.
