Field electron emission from amorphous carbon films grown in pure methane plasma

Large field enhancement at electrochemically grown quasi-1D Ni nanostructures with low-threshold cold-field electron emission

“…In our case, re-investigation of figure 3 indeed shows the emitter tip roughness is within 2% to 5% of the nanorod's length with a very sharp tip of the order of a few nanometers. Therefore considering d enhanced to be around 5 nm (5% of the average nanorod length of 100 nm) for our samples, the value of β TRFE th comes out as 4000 from equation (7), which is the same as that obtained from the experimental FN plot (β expt ). Thus the models proposed in equations ( 3) and ( 7) may be considered as feasible for nanostructured materials, especially for quasi-1D nanomaterials.…”

“…Recent advances in the fabrication of nanostructured materials, especially, zero-dimensional (0D) and quasi-one-dimensional (1D) materials such as carbon nanotubes (CNT) [1], Si-C nanorods [2], ZnO nanowires/rods [3], CuAlO 2 nanoparticles [4], etc, showed low macroscopic cold-field electron emission properties with a considerably low threshold and have become potential candidates for field emission displays (FED). Also, in the last decade, low-threshold field emission from carbon-based films such as diamond, diamondlike carbon (DLC), amorphous carbon (a:C) [5][6][7], etc, made them strong candidate materials for FEDs. Technologically, FEDs have been considered as strong candidates for low power panel applications because of their thin profile, high production efficiency, fast response, high brightness, wide operating temperature and excellent picture quality at lower cost [5].…”

Direct micropatterning of high dielectric BaTiO3 films by laser-induced pyrolysis with a nano-crystalline seeding technique

“…The results show that excess addition of PVP probably suppressed the crystallization. The weak and broad bands observed in the region of 1200-1600 cm À1 can be attributed to amorphous carbon [27], which was probably produced by the pyrolysis of organic groups such as PVP in the BT precursor. The spectrum at 10 kg/m 3 did not show the appearance of amorphous carbon but showed tetragonal peaks.…”

Scanning probe field emission current measurements on diamond-like carbon films treated by reactive ion etching

“…On the other hand, the field emission mechanism from the DLC surface has not yet been clarified. Experimental results of field emission have been split into the effect of the physical microstructure such as the surface roughness [12][13][14] and local enhancement of the electric field [14,18], or the effect of a chemical bond on the DLC surface such as impurity doping [15] and the ratio of sp 3 to sp 2 bonding. Milne et al [16] confirmed the improvement of the field emission property from the sp 3 -rich ta-C film treated by hydrogen and oxygen.…”
