Field emission display using nanowire field emitters

Abstract

Field emission display (FED) has advatanges in brightness, power consumption, color rendition, response time and operating temperature range. Early prototypes of triode-structured FED using Spindt-cathode were expensive to manufacture in large area. Using self-assembled one-dimensional nanomaterials such as carbon nanotubes (CNTs) and nanowires is a solution to this problem. The nanowire field emitters have the additional advantages of include better controlled electrical properties, feasibility of large area preparation and good field emission properties. In present talk, the recent results from our group about nanowire field emitters FED will be introduced. We prepared several one-dimensional nanowire emitters with excellent field emission performance. We also investigated a number of designs of gated microstructures and technical approaches for self-assembling nanowires inside these microstructures. Prototype field emission display devices have been fabricated. The results demonstrate the feasibility of large-area high-definition nanowire field emission display.
