Field emission properties of fractal surfaces
The density of emission current by a rough surface with fractal structure is analyzed. A possible experimental setup is modeled by an irregular emitting surface, iteratively generated by a fractional Brownian motion FBM algorithm with roughness or Hurst exponent H=0.3 and a far away plane representing the anode. The boundaries are held at a fixed potential difference and the Laplace’s equation,...
متن کاملInstrument for Characterization of Field Emission Properties of Nanostructured Surfaces
In this paper, an instrument for the characterization of field emission properties of nanostructured surfaces is described. First presented is an introduction to the theory of field emission followed by a short derivation of the key equations formulated by Fowler and Nordheim. The system is then described followed by an analysis of the system's performance and some example results.
متن کاملDirect fractal measurement and multifractal properties of fracture surfaces
A new method of fractal measurement, the projective covering method (PCM), is proposed in this Letter. Based on the measurements by means of a laser profilometer, the fractal dimension D E [2,3) of a fracture surface is directly estimated. The projective covering probability function is introduced to systematically analyze the multifractal behavior of the fracture surfaces. @ 1998 Elsevier Scie...
متن کاملField emission properties of patterned boron nanocones.
Large area patterned boron nanocones with low turn-on electric field of 2.8 V microm(-1) and low threshold electric field of 3.8 V microm(-1) were synthesized by a pre-manipulation to pattern the catalyst with a grid template as mask. The good field emission performance of patterned boron nanocones arise from the decreased screening effect and a favorable orientation of the nanocones. These res...
متن کاملAligned AlN Nanorods with Multi-tipped Surfaces-Growth, Field-Emission, and Cathodoluminescence Properties
Aluminum nitride, an important member of the group III nitrides with the highest bandgap of about 6.2 eV, has excellent thermal conductivity, good electrical resistance, low dielectric loss, high piezoelectric response, and ideal thermal expansion, matching that of silicon. The interest in field-emission (FE) applications of AlN materials has grown because they exhibit a negative electron affin...
