Field Emission from Hybrid Diamond-like Carbon and Carbon Nanotube Composite Structures

Hudson Zanin, +3 more
- 19 Nov 2013 - 
TL;DR: Field-emission tests of this new composite material show the typical low threshold voltages for carbon nanotube structures but with greatly increased emission current, better stability, and longer lifetime.
Book ChapterDOI

Review of Field Emission from Carbon Nanotubes: Highlighting Measuring Energy Spread

Marcos Henrique Mamoru Otsuka Hamanaka, +3 more
TL;DR: In this article, a review of the research on field emission properties of carbon nanotubes (CNTs), the basic properties of CNTs, the main emission properties with highlighting in energy spread and the work done in applying CNT for field emission microscopy (FEM).
Journal ArticleDOI

Combined effect of nitrogen doping and nanosteps on microcrystalline diamond films for improvement of field emission

U. A. Mengui, +6 more
- 15 Apr 2015 - 
TL;DR: In this article, nitrogen-doped microcrystalline diamond (N-MCD) films were grown on Si substrates using a hot filament reactor with methanol solution of urea as N source.
Journal ArticleDOI

Cristais líquidos colestéricos: a quiralidade revela as suas cores

Fernando Ely, +2 more
- 01 Jan 2007 - 
TL;DR: In this paper, the authors present easy experiments with a special class of chiral liquid crystals that show temperature-induced selective reflection of light (thermochromic effect), which allows undergraduate students better realize important properties of super and supramolecular systems.
Journal ArticleDOI

Máscaras mecânicas de sombra por eletrocorrosão para dispositivos eletro-ópticos

Iraci da Anunciação Pereira, +6 more
- 01 Jan 2014 - 
TL;DR: In this article, a shadow mask was used to evaporate cathode material to obtain an organic light emitting diode with active area of 9 mm2, which exhibited a turn-on voltage of 5 V and luminance of 14 cd/m2.
