Crystallization and grain growth characteristics of yttria-stabilized zirconia thin films grown by pulsed laser deposition

Effect of pulsed off-times on the reactive HiPIMS preparation of zirconia thin films

“…The value of n was determined to be 0.5 for an allowed transition or pointed that blue shift was related with high temperature which could promote film crystallization [25]. his positive shift was not monotonous and was interrupted at 2250 µs, thus yielding a low energy band gap of 5.86 eV.…”

Influence of anodization time on the surface modifications on α-Fe2O3photoanode upon anodization

“…Smaller grains which have a higher solubility than larger ones slowly dissolve and redeposit on the large crystals and simultaneously grain growth occurs. According to Heiroth et al, 33 grain growth process in polycrystalline material is driven by the minimization of the total grain boundary per area. During recrystallization and growth processes, the number of grain boundaries decreases due to the annihilation of small grains by grain boundary migration.…”

“…Microstructure, in particular the crystallinity, crystallite size, shape, spatial distribution, and morphology have an important influence on electrical, optical, and catalytic properties of semiconductor materials. 33 Therefore, a complete understanding of the influence of anodization process on the microstructure of a-Fe 2 O 3 photoanode is vital in improving the PEC performance of a-Fe 2 O 3 photoelectrode. This study aimed toward investigating the influence of anodization (exposure) time on the surface modifications on a-Fe 2 O 3 photoanode caused upon anodization in PEC cell.…”

X-ray absorption spectroscopy based investigation of local structure in yttria stabilized zirconia nanoparticles generated by laser evaporation method: Effect of pulsed vs CW mode of laser operation

“…The large FWHM and asymmetry of the Raman peaks in YSZ towards the low frequency side of the band are induced and dominated by the structural disorder associated with the high level of oxygen vacancy defects introduced in ZrO 2 lattice by the yttria doping. Heiroth et al also reported additional FWHM due to microstrain related contribution to peak broadening for the PLD grown YSZ films [36].…”
