Pulsed Laser Deposition (PLD) was used to grow chromium oxides (CrOx) on MgO(100), Al2O3(0001), SrTiO3(100), LaAlO3(100), and Si(100) under different growth conditions, including substrate temperature, O2 pressure, and laser fluence. SEM, AFM and XRD measurements show that various phases of CrOx films with different morphologies could be obtained on different substrates under the same growth conditions. Half-metallic CrO2 needle-like nanostructured films were only observed on MgO(100) under a special set of conditions.
