Indium Oxide Films

Field electron emission currents from nanostructured films always have unsatisfied stability. This paper introduces a photocurrent treatment technique to enhance the filed emission properties, and gives a kind of nanostructured indium oxide film suitable for the technique. The products were prepared on patterned ITO glass substrate by using chemical vapor deposition method. With the increase of reaction time, the morphologies of the films changed from cocoonlike particles to hybrid thin films, and finally flowerlike nanostructures were formed. Photocurrent and field electron emission characteristics of the products have been studied. After photocurrent treatment, the flowerlike indium oxide films show stable field emission current (fluctuation is less than 5%), low field emission threshold (at 7.5 V/m, the current density is 1 mA/cm2) and high enhancement factor of electrical field of 778. The field emission test results validated that the photocurrent treated flowerlike indium oxide films may act as electron emitters and applied in display applications.

Electron Emitters

Carbon nanotubes have a host of properties that make them excellent candidates for electron emitters. A significant amount of research has been conducted on nanotube-based field-emitters over the past two decades, and they have been investigated for devices ranging from flat-panel displays to vacuum tubes and electron microscopes. Other electron emission mechanisms from carbon nanotubes, such as photoemission, secondary emission, and thermionic emission, have also been studied, although to a lesser degree than field-emission. This paper presents an overview of the topic, with emphasis on these less-explored mechanisms, although field-emission is also discussed. We will see that not only is electron emission from nanotubes promising for electron-source applications, but also its study could reveal unusual phenomena and open the door to new devices that are not directly related to electron beams.
