Spatial variation of BSCCO elemental components deposited via fs-PLD

Abstract

Femtosecond laser has several advantages over nanosecond laser as it produces efficient thermal ablation and reduces the formation of molten particulates. Because of this, there has been an increasing interest in using femtosecond lasers in pulsed laser deposition over recent years. This work explores the use of a femtosecond pulsed laser to deposit BSCCO. BSCCO was deposited in different substrate positions to investigate the effect of spatial variation on the elemental ratio of deposited BSCCO. The experimental values were then compared with an existing collision-based model, a modified collision-based model, and a peak-fitting distribution. The peak fitting analysis has the nearest approximation to the experimental data among the three numerical models.
