We have fabricated a carbon nanotube field emission display (CNT-FED) panel with a 2-inch diagonal size by using a screen printing method and vacuum in-line sealing technology. The sealing temperature of the panel was around 390 °C and the vacuum level was obtained with 1.4×10torr at the sealing. When the field emission properties of a fabricated and sealed CNT-FED panel were characterized and ...

Background and Objectives: Industrial processes are the major sources of environmental pollutants. Oil & gas processing are one of the industries which emitting several air pollution matters in to the atmosphere. The obtained results of CO2 emission in one of the Gas Sweetening unit of Iranian south oil company based on the field and deskwork calculations is presented in this paper. Materials a...

We present a new grid of LTE model atmospheres for weakly magnetic (B <∼ 10 10 G) neutron stars, using opacity and equation of state data from the OPAL project and employing a fully frequency and angle dependent radiation transfer. We discuss the differences to earlier models, including a comparison with a detailed NLTE calculation. As a first application of the new synthetic spectra, we re-ana...

We report observations of field emission from self-catalyzed GaAs nanowires grown on Si (111). The measurements were taken inside a scanning electron microscope chamber with a nano-controlled tungsten tip functioning as anode. Experimental data were analyzed in the framework of the Fowler-Nordheim theory. We demonstrate stable current up to 10-7 A emitted from the tip of single nanowire, with a...

We present the first experimental proof of the influence of a nearby nano-sized metal object on the angular photon emission by a single molecule. A novel angular sensitive detection scheme is implemented in an existing near-field scanning optical microscope (NSOM). The positioning accuracy ( approximately 1 nm) of the NSOM allows a systematic investigation of the intensity ratio between two dif...

Recent studies of wide band-gap diamond field emission devices have realized superior performance and lifetime. However, theoretical studies using standard Fowler-Nordheim (FN) theory do not fully capture the physics of diamond semiconductor emitters as a result of the fitting parameters inherent to the FN approximation. The following research computationally models wide band-gap field emission...

This conference paper provides an overview of the material presented in two field electron emission tutorial lectures given at the 2016 Young Researchers' School in Vacuum Microand NanoElectronics, held in Saint-Petersburg in October 2016. This paper aims to indicate the scope and structure of the tutorials, and also where some of the related published material can be found. Keywords—field elec...
