Novel double pulsed laser method for synthesis of carbon nitride films

A new approach based on the use of the double laser pulse was proposed to improve the crystallinity of carbon nitride films producing by PLD method. A pairs of laser pulses with time delay of 10 µs were used for graphite ablation in nitrogen gas. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) methods were utilized for characterisation of carbon nitride films synthesised by common (single pulse) PLD and double pulse PLD techniques.
