Opto-electronic properties of poly-crystalline La doped BaSnO3 films deposited on quartz substrates

Highly conducting and transparent thin films of LaxBa1 - xSnO3 (x = 0, 0.01 and 0.05) were grown on quartz substrates via pulsed laser deposition. Conductivity increases in orders of magnitude upon vacuum annealing of the as-deposited films. This is attributed to the significant enhancement in carrier concentration due to the increased oxygen vacancy defects (VO center dot center dot

Automated summary

Highly conducting and transparent thin films of LaxBa1-xSnO3 were successfully grown on quartz substrates via pulsed laser deposition. The conductivity of the films increased significantly after vacuum annealing due to the enhanced carrier concentration from increased oxygen vacancy defects.
