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

控制碳纳米管的自组织形貌是为了将其应用于场发射（FE）型发光元件的电子发射体中。为了形成具有适当间距和数量密度的碳纳米管发射体，系统地研究了从自组织碳纳米管发射体到宏观器件的FE特性。通过多尺度评价；通过对碳纳米管生长的控制和器件结构的优化，大大改善了实现其有限元性能的制备条件。预计所获得的结果将应用于各种常规基材的可耐受工艺。

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.
