چکیده

The nitrogen doped amorphous carbon (a-C:N) thin films were synthesized for the first time by mixing of nitrogen gas, argon and ethanol precursor via a bias assisted pyrolysis-CVD in the range of 250 o C to 550 o C with fixed negative bias of -50V in 1h deposition. The a-C:N thin films were characterized by current-voltage measurement, UV/VIS spectrophotometer, surface profiler, and atomic force microscopy. The resistivity of a-C:N thin films in the range 250 o C-550 o C was 4.97x10 Ω.cm, 2.66x10 Ω.cm 1.974x10Ω.cm, 3.63x10Ω.cm, and 4.44x10Ω.cm, and 1.73x10Ω.cm, respectively. It was found that a-C:N thin films have responded with photon by created electron hole pair where the highest photo response of a-C:N film was found at 350 o C. The deposition temperatures with the help of constant dc voltage influenced the physical properties of a-C thin films.

Physical Properties of Reactively Sputter-Deposited C-N Thin Films

This work aims to prepare and study amorphous carbon nitride (CNx) films. Films were deposited by reactive magnetron radiofrequency (RF) sputtering from graphite target in argon and nitrogen mixture discharge at room temperature. The ratio of the gas flow rate was varied from 0.1 to 1. Deposited films were found to be amorphous. Highest Nitrogen concentration achieved was 42 atomic percent whic...

P-type properties of micro and nano-structured carbon films from hydrocarbon palm oil in photovoltaic heterojunction solar cell applications (16 Bold)

The micro and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the micro and nano structured films had particle size in the range of 382 nm to 689 nm and 28 to 34 nm, respectively. The energy-dispersive spectroscopy (EDS) showed the existing of carb...
