Influence of laser pulse energy on the microstructure and optical properties of Cu2ZnSnS4 films by one-step pulsed laser deposition

In this work; copper oxide films (CuO) were fabricated by PLD. The films were analyzed by UV-VIS absorption spectra and their thickness by using profilometer. Pulsed Nd:YAG laser was used for prepared CuO thin films under O2 gas environment with varying both pulse energy and annealing temperature. The optical properties of as-grown film such as optical transmittance spectrum, refractive index and energy gap has been measured experimentally and the effects of laser pulse energy and annealing temperature on it were studied. An inverse relationship between energy gap and both annealing temperature and pulse energy was observed.

Before And After

Silicon dioxide thin film of different thicknesses has been grown on glass substrate by pulsed laser deposition technique with and without annealing temperature under the vacuum pressure of 8×10-2 mbar. The optical properties such as the absorption, and transmission spectra have been studied for the prepared SiO2 thin film before and after annealing temperature. From the transmission spectra, the optical gap and linear refractive index of the SiO2 thin film was determined. The structure of the SiO2 thin film was tested with X-Ray diffraction, it was formed to be amorphous structure before annealing temperature. The effects of laser pulse energy on the optical properties has been studied before and after annealing temperature. It is found that almost optical properties depends on the laser pulse energy and increases with increasing laser pulse energy and they are enhanced with the annealing temperature. Keywords: SiO2 thin film, pulse laser deposition, annealing temperature.
