Structural Evolution of Nanostructured YBa2Cu3Ox Thin Films Formed by Pulsed Laser Glancing Angle Deposition

Abstract:

Article Preview

Nano-structured thin films of amorphous YBa2Cu3Ox were prepared by pulsed laser glancing angle deposition. Ambient oxygen pressure and laser fluence have a strong effect on the microstructure of the films. The films exhibit a structural evolution from isolated nanorods, through network of vertical nanocolumns, to nanoparticles fractal with increasing ambient oxygen pressures. Shadowing effect, surface diffusion and flux scattering by ambient gas play main roles in determining the structural evolution.
