Field emission in a microwave field*

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1995
This article deals with principal peculiarities of field electron emission in a microwave field. The adiabaticity problem in respect to the field emission process, experimental verification of the Fowler–Nordheim theory, and problem of maximum densities of the emission current are analyzed.

Development of field emission displays

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2004
Field emission displays (FED) are drawing attention as one of the most promising flat panel displays. Currently, the development stage of Spindt-type FEDs with Mo emitter is close to an end. The monocolor Spindt-type FEDs are being supplied to the market, and the color FEDs are ready for mass production.

Field Emission in Doped Nanotubes

Journal of Nanoscience and Nanotechnology, 2005
Doping into nanotubes is an attractive and significant way to tailor their electron transport and emission properties. This article reviews some recent experimental and theoretical advances in the studies of doping behaviors in carbon nanotubes and gallium nitrogen nanotubes, and doping effects on their field electron emission properties.

Field and thermionic-field emission in Schottky barriers

Solid-State Electronics, 1966
Abstract Field emission and thermionic-field (T-F) emission are considered as the phenomena responsible for the excess currents observed both in the forward and reverse directions of Schottky barriers formed on highly doped semiconductors. Voltage-current characteristics are derived for field and thermionic-field emission in the forward and reverse ...

Field emission monotron for THz emission

International Journal of Infrared and Millimeter Waves, 1997
Small-signal negative conductance of a field emission monotron was calculated, which was considerably higher than that of a thermionic monotron due to strong bunching of emitted electrons in a field emission. The amplification constant of 28dB/mm is achieved at THz wave region by applying the monotron to a distributed amplifier and is sufficient to ...

Field Emission and Field Ionization

1968
Both the field-ion microscope and the field-emission microscope are projection microscopes, in which the image is formed by radiation originating from a sharply pointed specimen and diverging from it to strike a fluorescent screen in a vacuum chamber. In the field-emission microscope the image is formed by electrons escaping from the negatively charged

Field emission from diamond particles studied by scanning field emission microscopy

Ultramicroscopy, 2003
Field emission properties from diamond particles (DPs) are studied. The DPs with thin chemically vapor deposited (CVD) diamond overcoat, dispersed onto metal substrate, essentially exhibit negative electron affinity (NEA). Field emission, approximately 1mA/cm(2) under a macroscopic electric field of 3.5kV/mm are observed.

SiC Field Emission Arrays

Journal of Wide Bandgap Materials, 2002
Summary form only given. Results from studies of the fabrication process and emissivity of FEAs of mold-type made of silicon carbide are presented. The gated and non-gated field emission arrays of SiC sharp emitter tips have been produced by the transfer mold technique.

Field emission properties of AlN nanostructures

2010 8th International Vacuum Electron Sources Conference and Nanocarbon, 2010
AIN with different morphologies, including thin film, nanowires, nanoneedles and nanochilies, depending on the controlled growth parameters, have been successfully synthesized by chemical vapor deposition technique. Field emission properties have been systematically studied.
