Fabrication of Nanomaterial Devices for Field Emission Applications

摘要：

Nanomaterials such as 1-dimensional nanowires and nanotubes and 2-dimensional graphene are the promising materials for novel device developments due to their unique physical and chemical properties.For field emission applications,nanomaterials are excellent candidate for an electron source by advantages of their small dimensions and high aspect ratios.In this study,we used GaN nanowires as the nanomaterials synthesized by Vapor-Liquid-Solid method.The field emission devices were then fabricated using the general Si microfabrication techniques.Moreover,the field emission properties of the GaN nanowires were characterized using cold field emission theory.It is demonstrated that the fabrication techniques shown in this study are efficient to fabricate field emission devices using nanomaterials.
