Electrical conductivity of nitride carbon films with different nitrogen content

Investigation of nitrogen doped diamond like carbon films as counter electrodes in dye sensitized solar cells

“…The Pt layer (150 nm) deposited by RF sputtering below the DLC (n-type) layer is deliberately chosen to increase the adhesiveness of DLC (n-type) on ITO and also to retain the good conductivity required between DLC (n-type) and ITO. Since a specific doping amount of nitrogen in DLC gives the highest conductivity [20], the concentration of nitrogen is monitored by depositing the DLC (n-type) layer for 1.5 min each with 0, 5, 10, 30 and 60 sccm of N 2 resulting in thicknesses of 165, 165, 198, 199, 165.5 nm, respectively. Hopping conduction is enhanced through N incorporation and the corresponding lattice relaxation.…”

“…and their band gap can be tuned by manipulating the sp 2 and sp 3 bonding ratio [17,18]. The electrical conductivity of DLC films can be improved by doping with nitrogen [19] to result in semi-conducting to highly conducting behavior [20,21]. DLC films are in use as antireflection and protective coatings of solar cells designed for space [22] while the nitrogen doped DLC films are used in similar p-n junction solar cells or schottky solar cells in combination with p-Si or ITO, respectively [23,24].…”

Structural, electrical, and optical properties of amorphous carbon nitride films prepared using a hybrid deposition technique

“…Their properties are strongly dependent on the deposition techniques employed in their fabrication [1][2]. Most a-CN x films prepared by chemical vapor deposition (CVD) have a nitrogen concentration of less than 0.3, and exhibit high hardness, optical transparency, and high resistivity [3][4][5][6][7]. In contrast, a-CN x films prepared by physical vapor deposition (PVD) have a higher nitrogen concentration [8][9][10].…”

High definition conductive carbon films from solution processing of nitrogen-containing oligomers

“…Benefiting from its hardness, chemical inertness, low friction coefficient, high refractive index, high thermal and electrical conductivity [1][2][3], they have widespread applications as protective coatings for optical windows, automobile parts, biomedical coatings, computer hard disks and micro-electrochemical devices (MEMs), but also for the coating of filler particles and antistatic treatments [1,4,5]. The attraction of a conjugated conductive, rather homogeneous carbon films lies in the essential absence of grain boundary effects and minimization of contact resistance.…”
